CVE-2007-4556 in opensymphony xwork

LogPulse has a published detection rule for this CVE: it raises a notable when someone tries to exploit it.

What the vulnerability is

Struts support in OpenSymphony XWork before 1.2.3, and 2.x before 2.0.4, as used in WebWork and Apache Struts, recursively evaluates all input as an Object-Graph Navigation Language (OGNL) expression when altSyntax is enabled, which allows remote attackers to cause a denial of service (infinite loop) or execute arbitrary code via form input beginning with a "%{" sequence and ending with a "}" character.

Affected software: opensymphony xwork
