CVE-2025-25766 is an arbitrary file upload vulnerability affecting MRCMS v3.1.2. The vulnerability exists in the component /file/savefile.do, allowing attackers to execute arbitrary code by uploading a crafted .jsp file. This type of vulnerability is classified as a medium severity issue, with a CVSS score of 4.8. It poses a real-world risk as it could lead to unauthorized code execution on the server, potentially compromising sensitive data and system integrity.
The vulnerability was published on February 21, 2025, and was classified under CWE-77, which refers to improper neutralization of special elements used in a command ('command injection'). With a medium exploitability score, it is important for organizations using MRCMS to evaluate their exposure and take necessary actions.
Currently, no known exploits exist for this vulnerability, but the potential for exploitation remains. Organizations should prioritize patching this vulnerability as part of their ongoing security measures.
Organizations should address this vulnerability promptly to mitigate potential risks.
Vulnerability Details
The vulnerability allows attackers to upload arbitrary files, specifically crafted .jsp files, which can lead to code execution. The CVSS score of 4.8 indicates a medium severity, with the following characteristics:
• Attack Vector: Network • Attack Complexity: High • Privileges Required: None • User Interaction: None • Confidentiality Impact: Low • Integrity Impact: Low • Availability Impact: None
The affected product is MRCMS v3.1.2, and remediation is necessary to prevent potential unauthorized access.
Technical Analysis
This vulnerability results from inadequate validation of uploaded files, which allows attackers to upload malicious files that can be executed by the server. The attack vector is through network access to the affected component, requiring no special privileges or user interaction.
Given the high attack complexity, it indicates the need for a sophisticated approach to exploit this vulnerability, making it more challenging for attackers compared to low-complexity vulnerabilities.
Risk & Impact Analysis
Risk to organizations includes potential unauthorized execution of code, leading to data breaches or system compromise. The potential blast radius could be significant if exploited, particularly if the MRCMS application is publicly accessible. Organizations should assess their deployment for exposure to this vulnerability in the context of their security posture.
With a CVSS score indicating medium severity, organizations should address this vulnerability in their priority patch cycle. The lack of current known exploits does not diminish the importance of patching, as the risk remains.
Exploitation Status
Signal | Status |
|---|---|
Known Exploit | No |
Public PoC | No |
Actively Exploited | No |
Ransomware Use | No |
Affected Versions
The affected version is MRCMS v3.1.2. All versions prior to vendor patch are vulnerable.
Mitigation & Remediation
Organizations should patch their MRCMS installations to version 3.1.3 or later to mitigate this vulnerability. If a patch is not available, organizations should implement strict input validation on file uploads and restrict the types of files that can be uploaded. Additionally, configuring security controls to monitor and log file uploads can help detect potential exploitation attempts.
Continuous security testing can also help identify weaknesses and ensure that remediation efforts are effective.
Detection Guidance
Organizations should monitor logs for any unauthorized file uploads and unusual file types. Behavioral anomalies related to file upload actions should also be flagged for review. Specific indicators to monitor include file uploads with extensions uncommon for the application and any execution of uploaded files.
AppSecure Threat Intelligence Insight
This vulnerability highlights the ongoing risks associated with file upload features in web applications. Security teams should prioritize file upload validation as part of their security posture. The lack of current known exploits does not imply safety; rather, it emphasizes the importance of proactive security assessments.
Organizations can benefit from a well-structured vulnerability management program that continuously evaluates their security landscape.
Additionally, adopting best practices in penetration testing can uncover similar vulnerabilities in other components.
In conclusion, organizations must remain vigilant in addressing vulnerabilities like CVE-2025-25766 to maintain a strong security posture.
