Detailsinfo

A vulnerability classified as critical was found in WAN Emulator 2.3. This vulnerability affects the function shell_exec of the file result.php. The manipulation of the argument pc with an unknown input leads to a os command injection vulnerability. The CWE definition for the vulnerability is CWE-78. The product constructs all or part of an OS command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended OS command when it is sent to a downstream component. As an impact it is known to affect confidentiality, integrity, and availability. CVE summarizes:

WAN Emulator v2.3 contains two unauthenticated command execution vulnerabilities. The result.php script calls shell_exec() with unsanitized input from the pc POST parameter, allowing remote attackers to execute arbitrary commands as the www-data user. The system also includes a SUID-root binary named dosu, which is vulnerable to command injection via its first argument. An attacker can exploit both flaws in sequence to achieve full remote code execution and escalate privileges to root.
