Technical ContextAI · show details
This vulnerability is classified as Server-Side Request Forgery (SSRF) (CWE-918), which allows attackers to make the server perform requests to unintended internal or external resources. MCCMS v2.7.0 has an SSRF vulnerability located in the index() method of the sys\apps\controllers\api\Gf.php file, where the pic parameter is processed. The pic parameter is decrypted using the sys_auth($pic, 1) function, which utilizes a hard-coded key Mc_Encryption_Key (bD2voYwPpNuJ7B8), defined in the db.php file. The decrypted URL is passed to the geturl() method, which uses cURL to make a request to the URL without proper security checks. An attacker can craft a malicious encrypted pic parameter, which, when decrypted, points to internal addresses or local file paths (such as http://127.0.0.1 or file://). By using the file:// protocol, the attacker can access arbitrary files on the local file system (e.g., file:///etc/passwd, file:///C:/Windows/System32/drivers/etc/hosts), allowing them to read sensitive configuration files, log files, and more, leading to information leakage or system exposure. The danger of this SSRF vulnerability includes accessing internal services and local file systems through protocols like http://, ftp://, and file://, which can result in sensitive data leakage, remote code execution, privilege escalation, or full system compromise, severely affecting the system's security and stability. Affected products include: Chshcms Mccms.

Executive ViewAI
Organizations using MCCMS v2.7.0 should be aware of notable risk from CVE-2025-50234, a server-side request forgery vulnerability rated CVSS 6.5. Users could be tricked into performing unintended actions. Proof-of-concept code is publicly available. Organizations should apply vendor updates when available and monitor for exploitation.
Apply vendor patch. If patching is delayed: implement egress filtering, block metadata endpoints.

What every action level means
SSVC AssessmentENISA
Priority Score
Attack Technique
Server-Side Request Forgery exploits applications that fetch remote resources based on user-supplied URLs.
Privilege escalation occurs when an attacker leverages flaws in access control mechanisms to gain permissions beyond what they were originally granted.
Information disclosure occurs when an application unintentionally exposes sensitive data that aids attackers in reconnaissance or directly compromises security.
Remote Code Execution represents the critical moment when an attacker successfully runs arbitrary code on a target system without physical access.
