FKIE_CVE-2011-1753
Vulnerability from fkie_nvd - Published: 2011-06-21 02:52 - Updated: 2026-06-16 23:29
Severity
Summary
expat_erl.c in ejabberd before 2.1.7 and 3.x before 3.0.0-alpha-3, and exmpp before 0.9.7, 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.
