Trailrunner7 (1100399) writes "The Apache Software Foundation released an advisory warning that a patch issued in March for a zero-day vulnerability in Apache Struts did not fully patch the bug in question. Officials said a new patch is in development and will be released likely within the next 72 hours, said Rene Gielen of the Apache Struts team. On March 2, a patch was made available for a ClassLoader vulnerability in Struts up to version 188.8.131.52. An attacker would be able to manipulate the ClassLoader via request parameters. Apache said the fix was insufficient to repair the vulnerability."
