CVE-2025-23561 is a medium-severity vulnerability classified as a Cross-site Scripting (XSS) issue, specifically an improper neutralization of input during web page generation. This vulnerability affects the robertkay MLL Audio Player MP3 Ajax plugin, allowing attackers to exploit stored XSS, which can lead to unauthorized data access or manipulation. The vulnerability exists in versions from n/a through 0.7.
The CVSS score for this vulnerability is 6.5, indicating a medium level of severity. This score reflects the potential impact on confidentiality, integrity, and availability, categorized as low. Organizations utilizing the affected MLL Audio Player MP3 Ajax should be aware of the potential risks and the urgency to address them.
Risk to organizations includes the possibility of attackers leveraging this vulnerability to execute malicious scripts in the context of the user’s browser. Such exploitation could lead to data theft, session hijacking, or other malicious activities that compromise user security. Given the nature of this vulnerability, organizations should prioritize patching immediately.
This vulnerability was published on February 3, 2025, and is currently marked as deferred. As such, there are no known public exploits or proof of concept available at this time, but vigilance is necessary as security measures are evaluated and implemented.
Vulnerability Details
The vulnerability allows for Cross-site Scripting (XSS) exploitation due to improper input handling in the MLL Audio Player MP3 Ajax plugin. This issue affects all versions from n/a to 0.7. The vulnerability falls under the CWE classification CWE-79, which specifically addresses improper neutralization of input in web applications.
The CVSS score of 6.5 indicates a medium severity, with an attack vector of network, low attack complexity, and requiring low privileges and user interaction. The potential impacts on confidentiality, integrity, and availability are all rated as low, suggesting that while the risk is present, it may not lead to severe consequences without further exploitation.
Technical Analysis
The root cause of this vulnerability is inadequate input validation within the plugin's web page generation process. Attackers may exploit this flaw through a crafted payload, leading to stored XSS. The attack vector is network-based, which means that the exploit can be executed remotely.
The attack complexity is low, and the privileges required for exploitation are also low, indicating that an attacker does not need elevated access to perform an attack. User interaction is required as the victim needs to visit a web page that includes the malicious payload.
The impact on confidentiality, integrity, and availability is rated low, suggesting that while the vulnerability can be exploited, the overall damage may be limited if adequate security measures are in place.
Risk & Impact Analysis
Real-world deployment risk includes the potential for attackers to execute malicious scripts, leading to unauthorized access to sensitive information or user accounts. Organizations utilizing the affected MLL Audio Player MP3 Ajax should consider the implications of this vulnerability on their users and data.
The blast radius potential is significant, as multiple users could be affected if the vulnerability is exploited. Given the nature of stored XSS, an attacker can embed malicious scripts that affect all users who access the compromised web page.
Urgency assessment based on the CVSS score and the potential for exploitation suggests that organizations should address this vulnerability in their priority patch cycle. The low EPSS score indicates a lower likelihood of exploitation, but the potential impact remains a concern.
