| विवरण |
Remote Code Execution via Content Filter Bypass: A critical vulnerability exists in the DedeCMS backend tag file editing functionality that allows authenticated administrators to bypass content filtering mechanisms and achieve arbitrary code execution on the server.
The vulnerability exploits a weakness in the content filtering logic that fails to detect indirect function calls through PHP callback functions like usort(), allowing attackers to execute system commands despite the presence of security filters.
Vulnerability Functionality:
- Content Filter Bypass: Uses PHP callback functions to circumvent variable function detection
- String Concatenation: Bypasses keyword blacklist by splitting dangerous function names
- Remote Code Execution: Executes arbitrary system commands through the usort() callback mechanism
- Persistent Access: Malicious code is stored as a tag library file for repeated access |
