Cisco Jabber Extensible Communications Platform (aka Jabber XCP) 2.x through 5.4.x before 5.4.0.27581 and 5.8.x before 5.8.1.27561 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 ID CSCtq78106, a similar issue to CVE-2003-1564.

Security readout for executives and security teams

CVE-2011-3287 is a denial-of-service flaw in Cisco Jabber XCP XML processing. A remote attacker could send a specially crafted XML document that exhausts memory and CPU and may crash a process, disrupting collaboration or presence services. Exposure is most likely in organizations still running the listed legacy Cisco Jabber XCP releases. The source bundle does not provide CPEs, deployment details, or severity scoring, so exact exposure depends on asset inventory and service reachability. Prioritize where Jabber XCP supports critical communications or is reachable by many users. This is an availability issue, not documented as data theft or code execution in the supplied sources. Mitigation focus: Upgrade affected 5.4.x deployments to 5.4.0.27581 or later.; Upgrade affected 5.8.x deployments to 5.8.1.27561 or later.; Check Cisco advisory guidance for fixed release paths and operational caveats..
