CVE-2022-27778 4 Haxx, Netapp, Oracle and 1 more 19 Curl, Active Iq Unified Manager, Bh500s Firmware and 16 more 2024-03-27 5.8 MEDIUM 8.1 HIGH
A use of incorrectly resolved name vulnerability fixed in 7.83.1 might remove the wrong file when `--no-clobber` is used together with `--remove-on-error`.
CVE-2022-27779 3 Haxx, Netapp, Splunk 15 Curl, Clustered Data Ontap, H300s and 12 more 2024-03-27 5.0 MEDIUM 5.3 MEDIUM
libcurl wrongly allows cookies to be set for Top Level Domains (TLDs) if thehost name is provided with a trailing dot.curl can be told to receive and send cookies. curl's "cookie engine" can bebuilt with or without [Public Suffix List](https://publicsuffix.org/)awareness. If PSL support not provided, a more rudimentary check exists to atleast prevent cookies from being set on TLDs. This check was broken if thehost name in the URL uses a trailing dot.This can allow arbitrary sites to set cookies that then would get sent to adifferent and unrelated site or domain.
CVE-2022-27780 3 Haxx, Netapp, Splunk 15 Curl, Clustered Data Ontap, H300s and 12 more 2024-03-27 5.0 MEDIUM 7.5 HIGH
The curl URL parser wrongly accepts percent-encoded URL separators like '/'when decoding the host name part of a URL, making it a *different* URL usingthe wrong host name when it is later retrieved.For example, a URL like `http://example.com%2F127.0.0.1/`, would be allowed bythe parser and get transposed into `http://example.com/127.0.0.1/`. This flawcan be used to circumvent filters, checks and more.
CVE-2022-27781 4 Debian, Haxx, Netapp and 1 more 16 Debian Linux, Curl, Clustered Data Ontap and 13 more 2024-03-27 5.0 MEDIUM 7.5 HIGH
libcurl provides the `CURLOPT_CERTINFO` option to allow applications torequest details to be returned about a server's certificate chain.Due to an erroneous function, a malicious server could make libcurl built withNSS get stuck in a never-ending busy-loop when trying to retrieve thatinformation.
CVE-2022-27782 3 Debian, Haxx, Splunk 3 Debian Linux, Curl, Universal Forwarder 2024-03-27 5.0 MEDIUM 7.5 HIGH
libcurl would reuse a previously created connection even when a TLS or SSHrelated option had been changed that should have prohibited reuse.libcurl keeps previously used connections in a connection pool for subsequenttransfers to reuse if one of them matches the setup. However, several TLS andSSH settings were left out from the configuration match checks, making themmatch too easily.
CVE-2022-30115 3 Haxx, Netapp, Splunk 15 Curl, Clustered Data Ontap, H300s and 12 more 2024-03-27 4.0 MEDIUM 4.3 MEDIUM
Using its HSTS support, curl can be instructed to use HTTPS directly insteadof using an insecure clear-text HTTP step even when HTTP is provided in theURL. This mechanism could be bypassed if the host name in the given URL used atrailing dot while not using one when it built the HSTS cache. Or the otherway around - by having the trailing dot in the HSTS cache and *not* using thetrailing dot in the URL.
CVE-2022-32205 7 Apple, Debian, Fedoraproject and 4 more 29 Macos, Debian Linux, Fedora and 26 more 2024-03-27 4.3 MEDIUM 4.3 MEDIUM
A malicious server can serve excessive amounts of `Set-Cookie:` headers in a HTTP response to curl and curl < 7.84.0 stores all of them. A sufficiently large amount of (big) cookies make subsequent HTTP requests to this, or other servers to which the cookies match, create requests that become larger than the threshold that curl uses internally to avoid sending crazy large requests (1048576 bytes) and instead returns an error.This denial state might remain for as long as the same cookies are kept, match and haven't expired. Due to cookie matching rules, a server on `foo.example.com` can set cookies that also would match for `bar.example.com`, making it it possible for a "sister server" to effectively cause a denial of service for a sibling site on the same second level domain using this method.
CVE-2022-32206 6 Debian, Fedoraproject, Haxx and 3 more 30 Debian Linux, Fedora, Curl and 27 more 2024-03-27 4.3 MEDIUM 6.5 MEDIUM
curl < 7.84.0 supports "chained" HTTP compression algorithms, meaning that a serverresponse can be compressed multiple times and potentially with different algorithms. The number of acceptable "links" in this "decompression chain" was unbounded, allowing a malicious server to insert a virtually unlimited number of compression steps.The use of such a decompression chain could result in a "malloc bomb", makingcurl end up spending enormous amounts of allocated heap memory, or trying toand returning out of memory errors.
CVE-2022-32207 6 Apple, Debian, Fedoraproject and 3 more 19 Macos, Debian Linux, Fedora and 16 more 2024-03-27 7.5 HIGH 9.8 CRITICAL
When curl < 7.84.0 saves cookies, alt-svc and hsts data to local files, it makes the operation atomic by finalizing the operation with a rename from a temporary name to the final target file name.In that rename operation, it might accidentally *widen* the permissions for the target file, leaving the updated file accessible to more users than intended.
CVE-2022-32208 6 Apple, Debian, Fedoraproject and 3 more 19 Macos, Debian Linux, Fedora and 16 more 2024-03-27 4.3 MEDIUM 5.9 MEDIUM
When curl < 7.84.0 does FTP transfers secured by krb5, it handles message verification failures wrongly. This flaw makes it possible for a Man-In-The-Middle attack to go unnoticed and even allows it to inject data to the client.
CVE-2022-35252 5 Apple, Debian, Haxx and 2 more 18 Macos, Debian Linux, Curl and 15 more 2024-03-27 N/A 3.7 LOW
When curl is used to retrieve and parse cookies from a HTTP(S) server, itaccepts cookies using control codes that when later are sent back to a HTTPserver might make the server return 400 responses. Effectively allowing a"sister site" to deny service to all siblings.
CVE-2022-32221 5 Apple, Debian, Haxx and 2 more 13 Macos, Debian Linux, Curl and 10 more 2024-03-27 N/A 9.8 CRITICAL
When doing HTTP(S) transfers, libcurl might erroneously use the read callback (`CURLOPT_READFUNCTION`) to ask for data to send, even when the `CURLOPT_POSTFIELDS` option has been set, if the same handle previously was used to issue a `PUT` request which used that callback. This flaw may surprise the application and cause it to misbehave and either send off the wrong data or use memory after free or similar in the subsequent `POST` request. The problem exists in the logic for a reused handle when it is changed from a PUT to a POST.
CVE-2022-35260 4 Apple, Haxx, Netapp and 1 more 12 Macos, Curl, Clustered Data Ontap and 9 more 2024-03-27 N/A 6.5 MEDIUM
curl can be told to parse a `.netrc` file for credentials. If that file endsin a line with 4095 consecutive non-white space letters and no newline, curlwould first read past the end of the stack-based buffer, and if the readworks, write a zero byte beyond its boundary.This will in most cases cause a segfault or similar, but circumstances might also cause different outcomes.If a malicious user can provide a custom netrc file to an application or otherwise affect its contents, this flaw could be used as denial-of-service.
CVE-2022-42915 5 Apple, Fedoraproject, Haxx and 2 more 13 Macos, Fedora, Curl and 10 more 2024-03-27 N/A 8.1 HIGH
curl before 7.86.0 has a double free. If curl is told to use an HTTP proxy for a transfer with a non-HTTP(S) URL, it sets up the connection to the remote server by issuing a CONNECT request to the proxy, and then tunnels the rest of the protocol through. An HTTP proxy might refuse this request (HTTP proxies often only allow outgoing connections to specific port numbers, like 443 for HTTPS) and instead return a non-200 status code to the client. Due to flaws in the error/cleanup handling, this could trigger a double free in curl if one of the following schemes were used in the URL for the transfer: dict, gopher, gophers, ldap, ldaps, rtmp, rtmps, or telnet. The earliest affected version is 7.77.0.
CVE-2022-42916 4 Apple, Fedoraproject, Haxx and 1 more 4 Macos, Fedora, Curl and 1 more 2024-03-27 N/A 7.5 HIGH
In curl before 7.86.0, the HSTS check could be bypassed to trick it into staying with HTTP. Using its HSTS support, curl can be instructed to use HTTPS directly (instead of using an insecure cleartext HTTP step) even when HTTP is provided in the URL. This mechanism could be bypassed if the host name in the given URL uses IDN characters that get replaced with ASCII counterparts as part of the IDN conversion, e.g., using the character UTF-8 U+3002 (IDEOGRAPHIC FULL STOP) instead of the common ASCII full stop of U+002E (.). The earliest affected version is 7.77.0 2021-05-26.
CVE-2022-43551 4 Fedoraproject, Haxx, Netapp and 1 more 7 Fedora, Curl, Active Iq Unified Manager and 4 more 2024-03-27 N/A 7.5 HIGH
A vulnerability exists in curl <7.87.0 HSTS check that could be bypassed to trick it to keep using HTTP. Using its HSTS support, curl can be instructed to use HTTPS instead of using an insecure clear-text HTTP step even when HTTP is provided in the URL. However, the HSTS mechanism could be bypassed if the host name in the given URL first uses IDN characters that get replaced to ASCII counterparts as part of the IDN conversion. Like using the character UTF-8 U+3002 (IDEOGRAPHIC FULL STOP) instead of the common ASCII full stop (U+002E) `.`. Then in a subsequent request, it does not detect the HSTS state and makes a clear text transfer. Because it would store the info IDN encoded but look for it IDN decoded.
CVE-2022-43552 3 Apple, Haxx, Splunk 3 Macos, Curl, Universal Forwarder 2024-03-27 N/A 5.9 MEDIUM
A use after free vulnerability exists in curl <7.87.0. Curl can be asked to *tunnel* virtually all protocols it supports through an HTTP proxy. HTTP proxies can (and often do) deny such tunnel operations. When getting denied to tunnel the specific protocols SMB or TELNET, curl would use a heap-allocated struct after it had been freed, in its transfer shutdown code path.
CVE-2023-23914 3 Haxx, Netapp, Splunk 12 Curl, Active Iq Unified Manager, Clustered Data Ontap and 9 more 2024-03-27 N/A 9.1 CRITICAL
A cleartext transmission of sensitive information vulnerability exists in curl <v7.88.0 that could cause HSTS functionality fail when multiple URLs are requested serially. Using its HSTS support, curl can be instructed to use HTTPS instead of usingan insecure clear-text HTTP step even when HTTP is provided in the URL. ThisHSTS mechanism would however surprisingly be ignored by subsequent transferswhen done on the same command line because the state would not be properlycarried on.
CVE-2023-23915 3 Haxx, Netapp, Splunk 12 Curl, Active Iq Unified Manager, Clustered Data Ontap and 9 more 2024-03-27 N/A 6.5 MEDIUM
A cleartext transmission of sensitive information vulnerability exists in curl <v7.88.0 that could cause HSTS functionality to behave incorrectly when multiple URLs are requested in parallel. Using its HSTS support, curl can be instructed to use HTTPS instead of using an insecure clear-text HTTP step even when HTTP is provided in the URL. This HSTS mechanism would however surprisingly fail when multiple transfers are done in parallel as the HSTS cache file gets overwritten by the most recentlycompleted transfer. A later HTTP-only transfer to the earlier host name would then *not* get upgraded properly to HSTS.
CVE-2023-23916 5 Debian, Fedoraproject, Haxx and 2 more 13 Debian Linux, Fedora, Curl and 10 more 2024-03-27 N/A 6.5 MEDIUM
An allocation of resources without limits or throttling vulnerability exists in curl <v7.88.0 based on the "chained" HTTP compression algorithms, meaning that a server response can be compressed multiple times and potentially with differentalgorithms. The number of acceptable "links" in this "decompression chain" wascapped, but the cap was implemented on a per-header basis allowing a maliciousserver to insert a virtually unlimited number of compression steps simply byusing many headers. The use of such a decompression chain could result in a "malloc bomb", making curl end up spending enormous amounts of allocated heap memory, or trying to and returning out of memory errors.
