CVE-2025-0557: Medium Vulnerability in Hyland Alfresco Community Edition and Alfresco Enterprise Edition

A vulnerability classified as problematic has been found in Hyland Alfresco Community Edition and Alfresco Enterprise Edition up to 6.2.2. This vulnerability allows cross site scripting (XSS), which can be exploited remotely. The manipulation affects an unknown part of the file /share/s/ of the component URL Handler. As this exploit has been disclosed to the public, it poses a notable risk to organizations still using the affected versions.

The vulnerability has a CVSS score of 6.9, categorizing it as medium severity. This score indicates an attack vector that is network-based with low complexity and no privileges required. The presence of such vulnerabilities can lead to unauthorized access and data exposure, potentially compromising sensitive information.

Organizations should prioritize patching immediately, as the exploit is publicly available and may be leveraged by attackers. In light of this, it is recommended to upgrade to version 7.0 to remediate the vulnerability and enhance overall security posture.

Given the current threat landscape and the increasing frequency of similar attacks, it is crucial for security teams to remain vigilant. Continuous monitoring and timely updates are essential components of a robust security strategy.

Vulnerability Details

The vulnerability affects Hyland Alfresco Community Edition and Alfresco Enterprise Edition up to version 6.2.2. The official CVE description notes that the vulnerability results from improper handling of user input in the URL Handler component, leading to cross site scripting vulnerabilities.

The CWE classifications associated with this vulnerability are CWE-79 (Improper Neutralization of Input During Web Page Generation) and CWE-94 (Code Injection). Organizations utilizing these applications should assess their environments for exposure.

The vulnerability was published on January 18, 2025, and has been marked as deferred. However, the potential implications of this vulnerability necessitate immediate action from affected organizations.

Technical Analysis

The root cause of this vulnerability lies in inadequate validation of user input in the URL handling component. Attackers may leverage this vulnerability to execute arbitrary scripts in the context of the victim's browser, potentially leading to session hijacking, data theft, or other malicious actions.

The attack vector is network-based, allowing attackers to exploit the vulnerability remotely without any physical access to the affected systems. The attack complexity is low, requiring no special privileges or user interaction, which increases the risk of exploitation.

The integrity impact is classified as low, indicating that attackers may manipulate or alter data without detection. The confidentiality and availability impacts are minimal, but the potential for data exfiltration remains a significant concern.

Risk & Impact Analysis

Organizations using Hyland Alfresco software should be aware of the real-world deployment risks associated with this vulnerability. With a medium severity score, the risk to organizations includes potential unauthorized access, data leakage, and compromise of user sessions.

The blast radius potential is significant, especially for organizations that store sensitive information within Alfresco. Attackers exploiting this vulnerability may gain access to critical business data, which could lead to reputational damage and financial loss.

In light of the CVSS score of 6.9 and the absence of any known exploits currently being used in the wild, organizations should address this vulnerability in their priority patch cycle. Continuous monitoring and security assessments are essential to mitigate risks effectively.

Exploitation Status

Affected Versions

The affected versions include all Hyland Alfresco Community Edition and Alfresco Enterprise Edition versions prior to 7.0. Organizations using these versions are at risk and should plan to upgrade as soon as possible.

Mitigation & Remediation

Organizations should upgrade to version 7.0 of Hyland Alfresco to address this vulnerability. If immediate upgrading is not possible, implementing web application firewalls and input validation controls can help mitigate the risk of XSS attacks.

Monitoring web application logs for unusual behavior and user reports of suspicious activity can also provide early detection of potential exploitation attempts.

For further guidance, organizations may consider a security assessment through application security assessments to identify potential weaknesses.

Detection Guidance

Organizations should monitor their logs for indicators of cross site scripting attempts, such as unusual URL patterns and script injections. Behavioral anomalies in user sessions can also signal potential exploitation.

Additionally, ensure that any changes to web server configurations or application behaviors are logged and reviewed regularly to detect unauthorized modifications.

AppSecure Threat Intelligence Insight
