CVE-2024-1455 2024-04-16 N/A 5.9 MEDIUM
A vulnerability in the langchain-ai/langchain repository allows for a Billion Laughs Attack, a type of XML External Entity (XXE) exploitation. By nesting multiple layers of entities within an XML document, an attacker can cause the XML parser to consume excessive CPU and memory resources, leading to a denial of service (DoS).
CVE-2022-25857 2 Debian, Snakeyaml Project 2 Debian Linux, Snakeyaml 2024-03-15 N/A 7.5 HIGH
The package org.yaml:snakeyaml from 0 and before 1.31 are vulnerable to Denial of Service (DoS) due missing to nested depth limitation for collections.

libxml2 2.6.32 and earlier does not properly detect recursion during entity expansion in an attribute value, which allows context-dependent attackers to cause a denial of service (memory and CPU consumption) via a crafted XML document.
CVE-2011-1755 3 Apple, Fedoraproject, Jabberd2 4 Mac Os X, Mac Os X Server, Fedora and 1 more 2024-02-02 5.0 MEDIUM 7.5 HIGH
jabberd2 before 2.2.14 does not properly detect recursion during entity expansion, which allows remote attackers to cause a denial of service (memory and CPU consumption) via a crafted XML document containing a large number of nested entity references, a similar issue to CVE-2003-1564.
CVE-2009-1955 7 Apache, Apple, Canonical and 4 more 8 Apr-util, Http Server, Mac Os X and 5 more 2024-02-02 5.0 MEDIUM 7.5 HIGH
The expat XML parser in the apr_xml_* interface in xml/apr_xml.c in Apache APR-util before 1.3.7, as used in the mod_dav and mod_dav_svn modules in the Apache HTTP Server, allows remote attackers to cause a denial of service (memory consumption) via a crafted XML document containing a large number of nested entity references, as demonstrated by a PROPFIND request, a similar issue to CVE-2003-1564.
CVE-2003-1564 1 Xmlsoft 1 Libxml2 2024-02-02 9.3 HIGH 6.5 MEDIUM
libxml2, possibly before 2.5.0, does not properly detect recursion during entity expansion, which allows context-dependent attackers to cause a denial of service (memory and CPU consumption) via a crafted XML document containing a large number of nested entity references, aka the "billion laughs attack."
CVE-2023-20052 3 Cisco, Clamav, Stormshield 4 Secure Endpoint, Secure Endpoint Private Cloud, Clamav and 1 more 2024-01-25 N/A 5.3 MEDIUM
On Feb 15, 2023, the following vulnerability in the ClamAV scanning library was disclosed: A vulnerability in the DMG file parser of ClamAV versions 1.0.0 and earlier, 0.105.1 and earlier, and 0.103.7 and earlier could allow an unauthenticated, remote attacker to access sensitive information on an affected device. This vulnerability is due to enabling XML entity substitution that may result in XML external entity injection. An attacker could exploit this vulnerability by submitting a crafted DMG file to be scanned by ClamAV on an affected device. A successful exploit could allow the attacker to leak bytes from any file that may be read by the ClamAV scanning process.
CVE-2023-49967 1 Typecho 1 Typecho 2023-12-10 N/A 7.5 HIGH
Typecho v1.2.1 was discovered to be vulnerable to an XML Quadratic Blowup attack via the component /index.php/action/xmlrpc.
CVE-2023-41635 1 Grupposcai 1 Realgimm 2023-12-10 N/A 6.5 MEDIUM
A XML External Entity (XXE) vulnerability in the VerifichePeriodiche.aspx component of GruppoSCAI RealGimm v1.1.37p38 allows attackers to read any file in the filesystem via supplying a crafted XML file.
CVE-2023-38490 1 Getkirby 1 Kirby 2023-12-10 N/A 10.0 CRITICAL
Kirby is a content management system. A vulnerability in versions prior to 3.5.8.3, 3.6.6.3, 3.7.5.2, 3.8.4.1, and 3.9.6 only affects Kirby sites that use the `Xml` data handler (e.g. `Data::decode($string, 'xml')`) or the `Xml::parse()` method in site or plugin code. The Kirby core does not use any of the affected methods. XML External Entities (XXE) is a little used feature in the XML markup language that allows to include data from external files in an XML structure. If the name of the external file can be controlled by an attacker, this becomes a vulnerability that can be abused for various system impacts like the disclosure of internal or confidential data that is stored on the server (arbitrary file disclosure) or to perform network requests on behalf of the server (server-side request forgery, SSRF). Kirby's `Xml::parse()` method used PHP's `LIBXML_NOENT` constant, which enabled the processing of XML external entities during the parsing operation. The `Xml::parse()` method is used in the `Xml` data handler (e.g. `Data::decode($string, 'xml')`). Both the vulnerable method and the data handler are not used in the Kirby core. However they may be used in site or plugin code, e.g. to parse RSS feeds or other XML files. If those files are of an external origin (e.g. uploaded by a user or retrieved from an external URL), attackers may be able to include an external entity in the XML file that will then be processed in the parsing process. Kirby sites that don't use XML parsing in site or plugin code are *not* affected. The problem has been patched in Kirby 3.5.8.3, 3.6.6.3, 3.7.5.2, 3.8.4.1, and 3.9.6. In all of the mentioned releases, the maintainers have removed the `LIBXML_NOENT` constant as processing of external entities is out of scope of the parsing logic. This protects all uses of the method against the described vulnerability.
CVE-2023-3569 1 Phoenixcontact 14 Cloud Client 1101t-tx, Cloud Client 1101t-tx Firmware, Tc Cloud Client 1002-4g and 11 more 2023-12-10 N/A 4.9 MEDIUM
In PHOENIX CONTACTs TC ROUTER and TC CLOUD CLIENT in versions prior to 2.07.2 as well as CLOUD CLIENT 1101T-TX/TX prior to 2.06.10 an authenticated remote attacker with admin privileges could upload a crafted XML file which causes a denial-of-service.
CVE-2023-28118 1 Kaml Project 1 Kaml 2023-12-10 N/A 7.5 HIGH
kaml provides YAML support for kotlinx.serialization. Prior to version 0.53.0, applications that use kaml to parse untrusted input containing anchors and aliases may consume excessive memory and crash. Version 0.53.0 and later default to refusing to parse YAML documents containing anchors and aliases. There are no known workarounds.
CVE-2022-44641 2 Debian, Linaro 2 Debian Linux, Lava 2023-12-10 N/A 6.5 MEDIUM
In Linaro Automated Validation Architecture (LAVA) before 2022.11, users with valid credentials can submit crafted XMLRPC requests that cause a recursive XML entity expansion, leading to excessive use of memory on the server and a Denial of Service.
CVE-2022-33977 1 Untangle Project 1 Untangle 2023-12-10 N/A 7.5 HIGH
untangle is a python library to convert XML data to python objects. untangle versions 1.2.0 and earlier improperly restricts recursive entity references in DTDs. By exploiting this vulnerability, a remote unauthenticated attacker may cause a denial-of-service (DoS) condition on the server where the product is running.
CVE-2022-34430 1 Dell 1 Hybrid Client 2023-12-10 N/A 7.5 HIGH
Dell Hybrid Client below 1.8 version contains a Zip Bomb Vulnerability in UI. A guest privilege attacker could potentially exploit this vulnerability, leading to system files modification.
CVE-2022-34467 1 Mendix 1 Excel Importer 2023-12-10 4.0 MEDIUM 6.5 MEDIUM
A vulnerability has been identified in Mendix Excel Importer Module (Mendix 8 compatible) (All versions < V9.2.2), Mendix Excel Importer Module (Mendix 9 compatible) (All versions < V10.1.2). The affected component is vulnerable to XML Entity Expansion Injection. An attacker may use this to compromise the availability of the affected component.
CVE-2022-0217 1 Prosody 1 Prosody 2023-12-10 N/A 7.5 HIGH
It was discovered that an internal Prosody library to load XML based on libexpat does not properly restrict the XML features allowed in parsed XML data. Given suitable attacker input, this results in expansion of recursive entity references from DTDs (CWE-776). In addition, depending on the libexpat version used, it may also allow injections using XML External Entity References (CWE-611).
CVE-2022-26662 2 Debian, Tryton 3 Debian Linux, Proteus, Trytond 2023-12-10 5.0 MEDIUM 7.5 HIGH
