CVE-2025-0785: Medium Vulnerability in ESAFENET CDG

A vulnerability was found in ESAFENET CDG V5 and classified as problematic. This issue affects some unknown processing of the file /SysConfig.jsp. The manipulation of the argument help leads to cross site scripting. The attack may be initiated 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.

This vulnerability allows for cross-site scripting (XSS), which could have significant implications for users, especially if sensitive information is exposed.

The CVSS score for this vulnerability is 5.3, categorized as medium severity. The attack vector is classified as network-based with low attack complexity, meaning that exploitation could be straightforward for an attacker.

Risk to organizations includes the potential for attackers to execute arbitrary scripts in the context of a user's browser, potentially leading to session hijacking or data theft. Organizations should prioritize patching immediately.

Vulnerability Details

The vulnerability is attributed to the manipulation of the argument help within the /SysConfig.jsp file of ESAFENET CDG V5. It allows attackers to inject malicious scripts that can be executed when users access the affected page.

The CVSS base score of 5.3 indicates a medium severity level, with potential integrity impact described as low. The vulnerability was published on January 28, 2025, and classified under CWE-79 (Improper Neutralization of Input During Web Page Generation) and CWE-94 (Improper Control of Generation of Code ('Code Injection')).

Technical Analysis

The root cause of this vulnerability lies in insufficient input validation on user-supplied data, specifically in the handling of the help argument. The XSS vulnerability can be exploited by an attacker through a crafted request that manipulates the argument.

The attack vector is network-based, requiring low complexity to exploit, as it does not necessitate elevated privileges or user interaction. This vulnerability poses risks to confidentiality through the potential exposure of sensitive user information.

Risk & Impact Analysis

Organizations utilizing ESAFENET CDG V5 should assess their exposure to this vulnerability. Given the ease of exploitation and the potential impacts of XSS attacks, including data theft and reputational damage, it is crucial for organizations to take immediate action.

The vulnerability's low exploitation maturity indicates a lack of widespread exploitation; however, the public disclosure of the exploit increases the urgency for remediation efforts.

Exploitation Status

Affected Versions

The affected product is ESAFENET CDG version 5. All versions prior to vendor patch may be affected.

Mitigation & Remediation

Organizations should prioritize updating to the latest version of ESAFENET CDG. If a patch is not yet available, consider implementing input sanitization to mitigate the risk of XSS. Continuous monitoring for suspicious activities and network anomalies is also recommended.

Further security testing, such as continuous penetration testing, can help identify similar weaknesses.

Detection Guidance

Monitor logs for indicators of unauthorized access attempts and unusual script executions. Behavioral anomalies in user activity should also be flagged for further investigation.
