Vulnerabilities > Improper Restriction of Recursive Entity References in DTDs ('XML Entity Expansion')
| DATE | CVE | VULNERABILITY TITLE | RISK |
|---|---|---|---|
| 2019-09-10 | CVE-2019-12401 | XML Entity Expansion vulnerability in Apache Solr Solr versions 1.3.0 to 1.4.1, 3.1.0 to 3.6.2 and 4.0.0 to 4.10.4 are vulnerable to an XML resource consumption attack (a.k.a. | 7.5 |
| 2019-09-04 | CVE-2019-15903 | XML Entity Expansion vulnerability in multiple products 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. | 7.5 |
| 2019-06-12 | CVE-2019-5442 | XML Entity Expansion vulnerability in Pippo 1.12.0 XML Entity Expansion (Billion Laughs Attack) on Pippo 1.12.0 results in Denial of Service.Entities are created recursively and large amounts of heap memory is taken. | 5.0 |
| 2019-04-22 | CVE-2019-5427 | XML Entity Expansion vulnerability in multiple products c3p0 version < 0.9.5.4 may be exploited by a billion laughs attack when loading XML configuration due to missing protections against recursive entity expansion when loading configuration. | 7.5 |
| 2017-03-24 | CVE-2017-5644 | XML Entity Expansion vulnerability in Apache POI 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. | 7.1 |
| 2011-10-06 | CVE-2011-3288 | XML Entity Expansion vulnerability in Cisco Unified Presence 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. | 7.5 |
| 2011-06-21 | CVE-2011-1755 | XML Entity Expansion vulnerability in multiple products 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. | 7.5 |
| 2009-06-08 | CVE-2009-1955 | XML Entity Expansion vulnerability in multiple products 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. | 7.5 |
| 2008-08-27 | CVE-2008-3281 | XML Entity Expansion vulnerability in multiple products 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. | 6.5 |
| 2003-12-31 | CVE-2003-1564 | XML Entity Expansion vulnerability in Xmlsoft Libxml2 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." | 6.5 |
