This signature detects attempts to exploit a known vulnerability in TWiki, a Web-based collaboration application. Because TWiki does not properly check the rev parameter string for shell metacharacters, attackers can create a string containing quotes and shell commands, enabling them to execute arbitrary code with Web server privileges.
A remote command execution vulnerability affects the application. The revision control function of the TWikiUsers script uses the backtick shell metacharacter to construct a command line. An attacker may use a specially crafted URI to execute arbitrary commands through the shell. This attack would occur in the context of the vulnerable application and can facilitate unauthorized remote access.
