Comprehensive Technical Analysis of CVE-2025-28406

1. Vulnerability Assessment and Severity Evaluation

CVE ID: CVE-2025-28406 CVSS Score: 9.8

The vulnerability in RUoYi v.4.8.0 allows a remote attacker to escalate privileges via the jobLogId parameter. The CVSS score of 9.8 indicates a critical severity level, suggesting that this vulnerability poses a significant risk to systems running the affected software. The high score is likely due to the potential for complete system compromise and the ease of exploitation.

2. Potential Attack Vectors and Exploitation Methods

Attack Vectors:

• Remote Exploitation: The vulnerability can be exploited remotely, meaning an attacker does not need physical access to the system.
• Privilege Escalation: The primary attack vector involves manipulating the jobLogId parameter to gain elevated privileges on the system.

Exploitation Methods:

• Parameter Tampering: An attacker could send crafted requests to the application, manipulating the jobLogId parameter to bypass security checks and gain higher privileges.
• Automated Scripts: Attackers might use automated scripts to scan for vulnerable instances of RUoYi and exploit the vulnerability en masse.

3. Affected Systems and Software Versions

Affected Software:

• RUoYi v.4.8.0

Affected Systems:

• Any system running RUoYi v.4.8.0, including but not limited to:
  • Web servers hosting the RUoYi application
  • Cloud-based deployments of RUoYi
  • On-premises installations of RUoYi

4. Recommended Mitigation Strategies

Immediate Actions:

• Patching: Upgrade to a patched version of RUoYi as soon as it becomes available.
• Temporary Workarounds: Implement input validation and sanitization for the jobLogId parameter to mitigate the risk until a patch is applied.

Long-Term Strategies:

• Regular Updates: Ensure that all software components are regularly updated and patched.
• Security Audits: Conduct regular security audits and vulnerability assessments to identify and mitigate similar issues.
• Access Controls: Implement strict access controls and monitor for unusual privilege escalation activities.
