Description David Jorm 2013-10-31 05:18:21 UTC

Seam logging evaluates expression language (EL) statements in log messages. If an application includes user-provided strings in log messages directly via string concatenation, then a remote attacker could inject EL statements directly into the log messages, which would be evaluated on the server. If debug logging is enabled, Zanata performs logging of user-supplied strings using string concatenation. A remote attacker could use this flaw to execute arbitrary code in the context of the application server running Zanata.
