CVE-2025-28402

Comprehensive Technical Analysis of CVE-2025-28402

1. Vulnerability Assessment and Severity Evaluation

CVE ID: CVE-2025-28402 CVSS Score: 9.8

The vulnerability in RUoYi v.4.8.0 allows a remote attacker to escalate privileges via the jobId parameter. The CVSS score of 9.8 indicates a critical severity level. This high score is due to the potential for complete system compromise, the ease of exploitation, and the lack of user interaction required for a successful attack.

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: By manipulating the jobId parameter, an attacker can gain higher privileges, potentially leading to full administrative access.

Exploitation Methods:

• Parameter Manipulation: An attacker can send crafted requests to the vulnerable endpoint, manipulating the jobId parameter to escalate privileges.
• Automated Scripts: Attackers may use automated scripts to scan for vulnerable systems 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, application servers, and cloud-based deployments.

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 jobId 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 potential vulnerabilities.
• Access Controls: Implement strict access controls and least privilege principles to limit the impact of potential privilege escalation attacks.

5. Impact on Cybersecurity Landscape

Immediate Impact:

• Organizations using RUoYi v.4.8.0 are at high risk of privilege escalation attacks, which can lead to data breaches, unauthorized access, and system compromise.

Long-Term Impact:

• This vulnerability highlights the importance of robust input validation and the need for continuous monitoring and updating of software components.
• It underscores the necessity for organizations to have incident response plans in place to quickly address and mitigate such vulnerabilities.

6. Technical Details for Security Professionals

Vulnerability Details:

• The vulnerability exists in the handling of the jobId parameter in RUoYi v.4.8.0.
• An attacker can manipulate this parameter to bypass authentication and authorization checks, leading to privilege escalation.

Exploitation Steps:

1. Identify Vulnerable Endpoint: Determine the endpoint that processes the jobId parameter.
2. Craft Malicious Request: Create a request with a manipulated jobId value designed to escalate privileges.
3. Send Request: Send the crafted request to the vulnerable endpoint.
4. Gain Elevated Privileges: If successful, the attacker gains elevated privileges on the system.

Detection and Monitoring:

• Log Analysis: Monitor logs for unusual activity related to the jobId parameter.
• Intrusion Detection Systems (IDS): Implement IDS to detect and alert on suspicious requests targeting the jobId parameter.
• Network Monitoring: Use network monitoring tools to identify and block malicious traffic targeting the vulnerable endpoint.

Conclusion: CVE-2025-28402 represents a critical vulnerability in RUoYi v.4.8.0 that can be exploited for privilege escalation. Organizations must prioritize patching and implementing robust security measures to mitigate the risk. Continuous monitoring and regular security audits are essential to protect against such vulnerabilities and maintain a strong cybersecurity posture.
