Vulnerability Assessment

Weakness	CWE CWE-74 OWASP Top 10:2025 A05:2025 - Injection ASVS 5.0 V1 - Encoding and Sanitization Input neutralization, injection prevention
Exploitation Conditions	Exploitation requires authentication with high privileges (administrator role) to the Administrative Panel. The addPost function must be accessible over the network; no non-default configurations are needed beyond standard admin access. No user interaction is required.
Impact	This vulnerability requires high privileges (administrative access), limiting real-world risk despite a network attack vector. The CVSS 4.0 base score includes low confidentiality, integrity, and availability impacts (VC:L/VI:L/VA:L), and the exploit maturity is proof-of-concept only (E:P). EPSS score of 0.06% (19th percentile) indicates low likelihood of exploitation. No active exploitation has been reported. The product is end-of-life, so no patch will be released. The overall risk is low because the high privilege requirement severely constrains the attack surface, and impact is limited.
Exploit ScenarioDerived	An attacker who has obtained valid administrator credentials (e.g., via credential theft or brute-force) accesses the SyCms admin panel and sends a maliciously crafted request to the addPost endpoint. This injects PHP code that is executed on the server, enabling limited manipulation of data or system behavior.

Monitor Track and reassess. Why: LOW severity (CVSS 0.1-3.9).

AnalysisAIv1 – Jul 27, 2026

Code injection in the Administrative Panel of SyCms allows remote authenticated administrators to execute arbitrary code. The vulnerability resides in the addPost function of FileManageController.class.php, permitting an attacker with high privileges to inject and run malicious PHP. The product is unmaintained and no patch is available, though public exploit code exists.

RemediationAI

No vendor patch is available as the project is unmaintained. Immediate remediation is not possible. As a compensating control, restrict access to the administrative panel to trusted users and network segments only, ideally via IP whitelisting or firewall rules. This prevents remote exploitation but does not eliminate the vulnerability. Long-term, migrate to a supported content management system.

Affected ProductsAI

SyCms (shanyu) using a rolling release model up to commit a242ef2d194e8bb249dc175e7c49f2c1673ec921. The project is no longer supported, and the maintainer has not responded to the reported issue. The Gitee issue IDCEWG documents the vulnerability.

Technical ContextAI · show details

The vulnerability is a CWE-74 injection flaw in the PHP-based SyCms. The affected component handles file management tasks within the admin panel, where user-supplied input to the addPost function is not properly sanitized before being used in a downstream context, enabling code injection. No CPE identifiers are provided, but the codebase is identified up to commit a242ef2d194e8bb249dc175e7c49f2c1673ec921.
