CVE-2025-23641 is a medium severity vulnerability associated with improper neutralization of input during web page generation, specifically a Cross-site Scripting (XSS) vulnerability in PowieT Powie's pLinks PagePeeker plugin. This vulnerability allows for DOM-based XSS, which could be leveraged by attackers to execute arbitrary scripts in the context of the user's browser. The issue affects versions of the plugin from n/a through 1.0.2.
The CVSS score for this vulnerability is 6.5, indicating a medium level of risk. The attack vector is network-based, meaning that successful exploitation could occur remotely without requiring physical access to the affected system. Given the nature of XSS attacks, user interaction is required for exploitation, which adds a layer of complexity to the attack.
As of now, there are no known public exploits for this vulnerability, and it has not been added to the Known Exploited Vulnerabilities (KEV) catalog. However, organizations should remain vigilant, as the absence of known exploits does not eliminate the risk posed by this vulnerability.
Organizations should prioritize patching immediately to mitigate potential exploitation risks associated with this vulnerability. Regular updates and monitoring of installed plugins are critical to maintaining a secure environment.
Vulnerability Details
The vulnerability is classified as CWE-79, which pertains to improper neutralization of input during web page generation. This results in the ability to inject malicious scripts into web pages viewed by users. The specifics of the vulnerability can lead to unauthorized data access or manipulation.
The vulnerability was published on January 16, 2025, and remains classified as deferred. This means that while the vulnerability has been identified, there may not be an immediate fix or remediation available as of the last update.
Technical Analysis
As this vulnerability allows for DOM-based XSS, the root cause lies in the failure to properly sanitize user input during the web page generation process. Attackers may exploit this vulnerability by crafting a malicious payload that is executed when users interact with compromised pages.
The attack vector is classified as network-based, with low attack complexity, meaning that the vulnerability could be exploited by relatively unsophisticated attackers. The required privileges are low, as attackers do not need elevated access to exploit the vulnerability. User interaction is necessary, which means that the user must perform an action, such as clicking a link, to trigger the attack.
The impact on confidentiality, integrity, and availability is low, indicating that while the vulnerability poses a risk, it may not lead to catastrophic results. However, the potential for unauthorized script execution could lead to compromised user sessions or data leaks.
Risk & Impact Analysis
Risk to organizations includes potential unauthorized access to sensitive user data and the ability for attackers to impersonate users. The blast radius could be significant if the vulnerability is exploited on sites with a large user base, as the attack could spread quickly across affected platforms.
Considering the CVSS score of 6.5, organizations should address this vulnerability in their priority patch cycle. Regular security assessments and vulnerability management practices should be in place to identify and remediate such risks.
The current exploitation status indicates that this vulnerability is not actively exploited in the wild, but organizations should remain cautious and monitor for any updates regarding this vulnerability.
Exploitation Status
Signal | Status |
|---|---|
Known Exploit | No |
Public PoC | No |
Actively Exploited | No |
Ransomware Use | No |
Affected Versions
The affected product is PowieT Powie's pLinks PagePeeker plugin, specifically versions from n/a up to and including 1.0.2. Organizations using this plugin should ensure they are running the latest version to protect against this vulnerability.
Mitigation & Remediation
Organizations should update to the latest version of PowieT Powie's pLinks PagePeeker plugin to mitigate this vulnerability. Regular patch management practices should be established to ensure all software components are kept up to date.
In addition to patching, organizations should review their web application security posture and consider implementing additional security measures such as input validation, output encoding, and content security policies to further reduce the risk of XSS vulnerabilities.
For organizations without the capability to implement immediate patches, it is recommended to review and tighten access controls to limit exposure until vulnerabilities can be addressed.
Continuous penetration testing can help validate the effectiveness of the implemented security measures.
Detection Guidance
Organizations should monitor logs for any signs of unusual behavior or unauthorized access attempts. Specifically, look for patterns of suspicious input that could indicate an attempt to exploit the XSS vulnerability.
Behavioral anomalies such as unexpected script execution or redirection to malicious sites should also be investigated promptly.
