CVE-2011-1753 is a vulnerability of currently unknown severity. 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.. EPSS estimates a 2.13% chance of exploitation in the next 30 days.
