The Trend Micro InterScan Web Security Virtual Appliance (IWSVA) is affected by a remote code execution vulnerability. A stack-based buffer overflow condition exists in the DecryptPasswd function in libuiauutil.so due to improper validation of user-supplied data before copying it to a fixed-size, stack-based buffer via the strcpy function. An unauthenticated, remote attacker can exploit this, via a specially crafted HTTP message, to cause a denial of service condition or the execution of arbitrary code.
Note that the appliance is reportedly affected by other vulnerabilities; however, this plugin has not tested for those issues.
