A vulnerability, which was classified as problematic, was found in CmsEasy 7.7.7.9. Affected is the function deleteimg_action in the library lib/admin/file_admin.php. The manipulation of the argument imgname leads to path traversal. It is possible to launch the attack remotely. The exploit has been disclosed to the public and may be used. The vendor was contacted early about this disclosure but did not respond in any way.
The CVSS score for this vulnerability is 5.3, indicating a medium severity level. This score reflects the potential impact on affected systems and the ease of exploitation. Organizations must assess the risk associated with this vulnerability to ensure robust security measures are in place.
Risk to organizations includes potential unauthorized access to sensitive data through path traversal, which could compromise the integrity of the system. Attackers may leverage this vulnerability to access files outside the intended directory, posing significant risks to the confidentiality and integrity of the data.
Organizations should prioritize patching immediately. The lack of response from the vendor regarding the vulnerability disclosure raises concerns about timely mitigation steps. Therefore, organizations using CmsEasy should take proactive measures to safeguard their systems.
Vulnerability Details
The vulnerability in CmsEasy is classified under CWE-22, which indicates a path traversal issue. The function deleteimg_action is vulnerable due to improper handling of the imgname argument, allowing attackers to traverse directories and access unauthorized files.
The CVSS score of 5.3 reflects a medium severity classification, indicating that exploitation is feasible with low complexity and requires low privileges. As such, this vulnerability is a significant concern for organizations utilizing the affected version.
The vulnerability was published on February 16, 2025, and it affects CmsEasy version 7.7.7.9. As the vendor has yet to respond to the disclosure, organizations must remain vigilant in monitoring their systems for potential exploitation.
Technical Analysis
The root cause of this vulnerability lies in the failure to validate user input properly. The deleteimg_action function does not sanitize the imgname parameter, allowing attackers to craft malicious requests that exploit the path traversal flaw.
The attack vector is network-based, meaning that attackers can exploit this vulnerability remotely without physical access to the vulnerable system. The attack complexity is low, requiring minimal effort to exploit this flaw.
Privileges required for exploitation are low, as the attacker does not need administrative or elevated permissions to launch an attack. User interaction is not required, further increasing the risk of successful exploitation.
The potential impacts of this vulnerability include low confidentiality impact, as sensitive data may be accessed, but integrity and availability impacts are none. Organizations must be aware that while the immediate impact may be limited, the potential for data exposure remains a concern.
Risk & Impact Analysis
Real-world deployment risk is significant, as this vulnerability can be exploited by remote attackers without authentication. The blast radius potential is high, as successful exploitation can lead to unauthorized access to sensitive files, potentially affecting the integrity of the application's data.
Organizations should assess their exposure to this vulnerability and prioritize patching based on the CVSS score. Given the medium severity of this vulnerability, it should be addressed in priority patch cycle to mitigate risks effectively.
Failure to remediate this vulnerability could lead to data breaches and loss of trust from customers, emphasizing the importance of addressing security issues promptly.

Affected Versions
The affected version is CmsEasy 7.7.7.9. Organizations running this version should take immediate action to mitigate the risks associated with this vulnerability. If version information is missing, it is recommended to state that all versions prior to vendor patch are affected.
Mitigation & Remediation
Organizations should prioritize patching to the latest version of CmsEasy as soon as it becomes available to address this vulnerability. If a patch is not available, consider implementing workarounds such as restricting access to the deleteimg_action function and monitoring for suspicious activity.
Configuration hardening, such as validating input and sanitizing file paths, is essential to prevent path traversal attacks. Additionally, network controls should be established to limit exposure to critical functions.
Regular monitoring for any anomalies or unauthorized access attempts is crucial in detecting potential exploitation attempts.
Penetration testing can also help identify weaknesses and validate the effectiveness of remediation efforts.
Detection Guidance
Organizations should monitor logs for indicators of exploitation, such as unusual requests to the deleteimg_action function or attempts to access unauthorized files. Behavioral anomalies that deviate from normal patterns can also indicate potential exploitation.
Network signatures corresponding to the exploit attempts should be implemented to detect any malicious activities. Additionally, changes to the system or application configurations should be monitored closely to identify unauthorized modifications.
AppSecure Threat Intelligence Insight
The long-term significance of this vulnerability lies in the potential for exploitation that can lead to unauthorized access and data breaches. Security teams must recognize the patterns of vulnerabilities that allow for remote exploitation and take proactive measures.
This vulnerability highlights the importance of input validation and proper handling of user inputs in web applications. Organizations should conduct regular security assessments to identify and remediate similar weaknesses.
To stay ahead of threats, security teams should engage in continuous education and training regarding secure coding practices and vulnerability management. Implementing a comprehensive vulnerability management program can significantly reduce the risk of future vulnerabilities.
Additionally, conducting regular penetration testing can help organizations identify security gaps and ensure the robustness of their security posture.
In conclusion, the CmsEasy vulnerability CVE-2025-1335 serves as a reminder of the ongoing threat landscape and the necessity for organizations to maintain vigilance and proactive security measures.
