CVE-2022-29482 1 Dena 1 Mobaoku-auction \& Flea Market 2022-06-23 4.3 MEDIUM 3.7 LOW
'Mobaoku-Auction&Flea Market' App for iOS versions prior to 5.5.16 improperly verifies server certificates, which may allow an attacker to eavesdrop on an encrypted communication via a man-in-the-middle attack.
CVE-2021-43848 1 Dena 1 H2o 2022-02-07 4.3 MEDIUM 5.9 MEDIUM
h2o is an open source http server. In code prior to the `8c0eca3` commit h2o may attempt to access uninitialized memory. When receiving QUIC frames in certain order, HTTP/3 server-side implementation of h2o can be misguided to treat uninitialized memory as HTTP/3 frames that have been received. When h2o is used as a reverse proxy, an attacker can abuse this vulnerability to send internal state of h2o to backend servers controlled by the attacker or third party. Also, if there is an HTTP endpoint that reflects the traffic sent from the client, an attacker can use that reflector to obtain internal state of h2o. This internal state includes traffic of other connections in unencrypted form and TLS session tickets. This vulnerability exists in h2o server with HTTP/3 support, between commit 93af138 and d1f0f65. None of the released versions of h2o are affected by this vulnerability. There are no known workarounds. Users of unreleased versions of h2o using HTTP/3 are advised to upgrade immediately.
CVE-2017-10868 1 Dena 1 H2o 2021-08-12 5.0 MEDIUM 7.5 HIGH
H2O version 2.2.2 and earlier allows remote attackers to cause a denial of service in the server via specially crafted HTTP/1 header.
CVE-2016-7835 2 Dena, H2o Project 2 H2o, H2o 2021-04-19 6.4 MEDIUM 9.1 CRITICAL
Use-after-free vulnerability in H2O allows remote attackers to cause a denial-of-service (DoS) or obtain server certificate private keys and possibly other information.
CVE-2017-10872 1 Dena 1 H2o 2021-04-19 4.0 MEDIUM 6.5 MEDIUM
H2O version 2.2.3 and earlier allows remote attackers to cause a denial of service in the server via unspecified vectors.
CVE-2017-10908 1 Dena 1 H2o 2021-04-19 5.0 MEDIUM 7.5 HIGH
H2O version 2.2.3 and earlier allows remote attackers to cause a denial of service in the server via specially crafted HTTP/2 header.
CVE-2018-0608 1 Dena 1 H2o 2021-04-19 7.5 HIGH 9.8 CRITICAL
Buffer overflow in H2O version 2.2.4 and earlier allows remote attackers to execute arbitrary code or cause a denial of service (DoS) via unspecified vectors.
CVE-2017-10869 1 Dena 1 H2o 2021-04-19 5.0 MEDIUM 7.5 HIGH
Buffer overflow in H2O version 2.2.2 and earlier allows remote attackers to cause a denial-of-service in the server via unspecified vectors.
CVE-2016-1133 1 Dena 1 H2o 2021-04-19 4.3 MEDIUM 3.7 LOW
CRLF injection vulnerability in the on_req function in lib/handler/redirect.c in H2O before 1.6.2 and 1.7.x before 1.7.0-beta3 allows remote attackers to inject arbitrary HTTP headers and conduct HTTP response splitting attacks via a crafted URI.
CVE-2016-4817 1 Dena 1 H2o 2021-04-19 5.0 MEDIUM 7.5 HIGH
lib/http2/connection.c in H2O before 1.7.3 and 2.x before 2.0.0-beta5 mishandles HTTP/2 disconnection, which allows remote attackers to cause a denial of service (use-after-free and application crash) or possibly execute arbitrary code via a crafted packet.
CVE-2016-4864 1 Dena 1 H2o 2019-02-26 5.0 MEDIUM 7.5 HIGH
H2O versions 2.0.3 and earlier and 2.1.0-beta2 and earlier allows remote attackers to cause a denial-of-service (DoS) via format string specifiers in a template file via fastcgi, mruby, proxy, redirect or reproxy.
CVE-2015-5638 1 Dena 1 H20 2015-09-23 4.3 MEDIUM N/A
Directory traversal vulnerability in H2O before 1.4.5 and 1.5.x before 1.5.0-beta2, when the file.dir directive is enabled, allows remote attackers to read arbitrary files via a crafted URL.
