CVE-2023-52426 1 Libexpat Project 1 Libexpat 2025-06-17 N/A 5.5 MEDIUM
libexpat through 2.5.0 allows recursive XML Entity Expansion if XML_DTD is undefined at compile time.
CVE-2019-15903 2 Libexpat Project, Python 2 Libexpat, Python 2025-05-30 5.0 MEDIUM 7.5 HIGH
In libexpat before 2.2.8, crafted XML input could fool the parser into changing from DTD parsing to document parsing too early; a consecutive call to XML_GetCurrentLineNumber (or XML_GetCurrentColumnNumber) then resulted in a heap-based buffer over-read.
CVE-2022-44641 1 Linaro 1 Lava 2025-04-29 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-2017-5644 1 Apache 1 Poi 2025-04-20 7.1 HIGH 5.5 MEDIUM
Apache POI in versions prior to release 3.15 allows remote attackers to cause a denial of service (CPU consumption) via a specially crafted OOXML file, aka an XML Entity Expansion (XEE) attack.
CVE-2011-3288 1 Cisco 1 Unified Presence 2025-04-11 7.8 HIGH 7.5 HIGH
Cisco Unified Presence before 8.5(4) does not properly detect recursion during entity expansion, which allows remote attackers to cause a denial of service (memory and CPU consumption, and process crash) via a crafted XML document containing a large number of nested entity references, aka Bug IDs CSCtq89842 and CSCtq88547, a similar issue to CVE-2003-1564.
CVE-2024-28757 3 Fedoraproject, Libexpat Project, Netapp 21 Fedora, Libexpat, Active Iq Unified Manager and 18 more 2025-03-28 N/A 7.5 HIGH
libexpat through 2.6.1 allows an XML Entity Expansion attack when there is isolated use of external parsers (created via XML_ExternalEntityParserCreate).
CVE-2022-28652 2 Apport Project, Canonical 2 Apport, Ubuntu Linux 2025-03-13 N/A 5.5 MEDIUM
~/.config/apport/settings parsing is vulnerable to "billion laughs" attack
CVE-2025-0617 2025-01-29 N/A 5.9 MEDIUM
An attacker with access to an HX 10.0.0 and previous versions, may send specially-crafted data to the HX console. The malicious detection would then trigger file parsing containing exponential entity expansions in the consumer process thus causing a Denial of Service.
CVE-2024-43398 2025-01-03 N/A 5.9 MEDIUM
REXML is an XML toolkit for Ruby. The REXML gem before 3.3.6 has a DoS vulnerability when it parses an XML that has many deep elements that have same local name attributes. If you need to parse untrusted XMLs with tree parser API like REXML::Document.new, you may be impacted to this vulnerability. If you use other parser APIs such as stream parser API and SAX2 parser API, this vulnerability is not affected. The REXML gem 3.3.6 or later include the patch to fix the vulnerability.
CVE-2021-1267 1 Cisco 1 Secure Firewall Management Center 2024-11-26 4.0 MEDIUM 4.3 MEDIUM
A vulnerability in the dashboard widget of Cisco Firepower Management Center (FMC) Software could allow an authenticated, remote attacker to cause a denial of service (DoS) condition on an affected device. The vulnerability is due to improper restrictions on XML entities. An attacker could exploit this vulnerability by crafting an XML-based widget on an affected server. A successful exploit could cause increased memory and CPU utilization, which could result in a DoS condition.
CVE-2024-28982 1 Hitachi 1 Pentaho Business Analytics Server 2024-11-21 N/A 7.1 HIGH
Hitachi Vantara Pentaho Business Analytics Server versions before 10.1.0.0 and 9.3.0.7, including 8.3.x do not correctly protect the ACL service endpoint of the Pentaho User Console against XML External Entity Reference.
CVE-2024-27142 2024-11-21 N/A 5.9 MEDIUM
Toshiba printers use XML communication for the API endpoint provided by the printer. For the endpoint, XML parsing library is used and it is vulnerable to a time-based blind XML External Entity (XXE) vulnerability. An attacker can DoS the printers. An attacker can exploit the XXE to retrieve information. As for the affected products/models/versions, see the reference URL.
CVE-2024-27141 2024-11-21 N/A 5.9 MEDIUM
Toshiba printers use XML communication for the API endpoint provided by the printer. For the endpoint, XML parsing library is used and it is vulnerable to a time-based blind XML External Entity (XXE) vulnerability. An attacker can DoS the printers by sending a HTTP request without authentication. An attacker can exploit the XXE to retrieve information. As for the affected products/models/versions, see the reference URL.
CVE-2024-1455 2024-11-21 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-2023-49967 1 Typecho 1 Typecho 2024-11-21 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 2024-11-21 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-2023-3569 1 Phoenixcontact 14 Cloud Client 1101t-tx, Cloud Client 1101t-tx Firmware, Tc Cloud Client 1002-4g and 11 more 2024-11-21 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-2023-38490 2024-11-21 N/A 6.8 MEDIUM
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-2023-28118 1 Kaml Project 1 Kaml 2024-11-21 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-2023-20052 3 Cisco, Clamav, Stormshield 4 Secure Endpoint, Secure Endpoint Private Cloud, Clamav and 1 more 2024-11-21 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.
