CVE-2025-51745, published on 2025-11-25, is a critical vulnerability (CVSS 9.8, CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H) discovered in jishenghua JSH_ERP 2.3.1. The flaw affects the /role/addcan endpoint, which is vulnerable to fastjson deserialization attacks, mapped to CWE-502 (Deserialization of Untrusted Data). This Java-based ERP system processes untrusted input insecurely, enabling exploitation through malicious serialized payloads.
The vulnerability can be exploited by any remote attacker with network access to the affected endpoint, requiring no privileges, user interaction, or special conditions due to its low attack complexity. Attackers can achieve high-impact outcomes, including full compromise of confidentiality, integrity, and availability, typically resulting in remote code execution via deserialization gadget chains in fastjson.

Mitigating Controls
Mitigating Controls (NIST 800-53 r5) AI
Developer testing and evaluation can uncover deserialization flaws before deployment.
Input validation directly stops deserialization of untrusted data by ensuring inputs are valid before processing.
Engineering principles such as safe deserialization and input sanitization structurally prevent the weakness from being introduced.
Integrity verification tools can detect malformed or tampered serialized data after the fact.

PR.PS-02 addresses only post-deployment updates/patching and cannot prevent introduction of unsafe deserialization code, yet it can remediate some instances when the flaw exists in outdated libraries or components.

Security testing includes validation of deserialization routines and the use of untrusted data, reducing the likelihood that unsafe object reconstruction will be deployed.
Requiring vetted libraries, regular updates and SAST before release reduces the likelihood that deserialization logic will accept and act on attacker-controlled serialized objects.
Regular scanning of third-party libraries and timely patching reduce the likelihood that unsafe deserialization vulnerabilities remain active.
