Vulnerabilities > Improper Restriction of Recursive Entity References in DTDs ('XML Entity Expansion')
| DATE | CVE | VULNERABILITY TITLE | RISK |
|---|---|---|---|
| 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. | 5.5 |
| 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 |
