ThinkPHP Remote Code Execution Vulnerability

ThinkPHP contains an unspecified vulnerability that allows for remote code execution via public//?s=index/\think\app/invokefunction&function=call_user_func_array&vars[0]=system&vars[1][]= followed by the command.

Added to KEV: 2021-11-03Federal patch deadline: 2022-05-03
Required Action (CISA)

Apply updates per vendor instructions.

Risk Analysis

This unspecified vulnerability in ThinkPHP allows for remote code execution through a specific URL parameter manipulation. The very high EPSS score of 0.94255 indicates a significant likelihood of exploitation, and its presence in the KEV confirms it is actively exploited.

This vulnerability is actively exploited in the wild, meaning that functional exploits are publicly available and being used by threat actors. The flaw is remotely exploitable via a crafted URL.

Recommended Action

Update ThinkPHP to a patched version. Implement input validation and sanitize all user-supplied data to prevent command injection and similar attacks.

Generated by the CTIWATCH analysis pipeline from this CVE's metadata (CVSS, EPSS, KEV status, exploit intelligence). Verify against vendor advisories before acting.

Technical Analysis

CVE-2019-9082 requires local access, meaning attackers must already have a foothold on the target system.

Exploitation requires some privileges, which limits the exposure to scenarios where an attacker has already gained initial access.

CISA has added CVE-2019-9082 to the Known Exploited Vulnerabilities (KEV) catalog, confirming active exploitation in the wild. U.S. federal agencies are required to patch this within the mandated timeframe, and all organizations should treat remediation as urgent.
