CVE-2025-23629 refers to a high-severity vulnerability classified as a Cross-site Scripting (XSS) issue. The vulnerability exists in the Gallerio plugin developed by Subhasis Laha, allowing attackers to execute malicious scripts in the context of a user's browser. This vulnerability allows reflected XSS, which can lead to unauthorized actions on behalf of users or data theft. The CVSS score is 7.1, indicating a high level of risk for affected organizations.
The affected versions of Gallerio are all versions prior to 1.0.1. Given the nature of XSS vulnerabilities, the potential impact can be significant, leading to data compromise and loss of user trust. Organizations using the Gallerio plugin are urged to take immediate action to apply available patches.
Currently, there are no known exploits or public proof of concepts associated with this vulnerability. However, organizations should not underestimate the risk, as the exploitation of XSS vulnerabilities is a common tactic among attackers.
Organizations should prioritize patching immediately to mitigate the risks associated with this vulnerability. Failure to address this issue may expose organizations to various attacks that could compromise their web applications.
Vulnerability Details
The CVE-2025-23629 vulnerability stems from improper neutralization of input during web page generation, allowing attackers to inject malicious scripts into legitimate web pages. The CVSS version 3.1 score of 7.1 indicates that the vulnerability is of high severity. The attack vector is network-based, requiring low complexity for exploitation and no privileges are required for an attacker. User interaction is necessary, as the attack relies on the victim clicking a malicious link. The impacts on confidentiality, integrity, and availability are rated as low.
Technical Analysis
Root cause analysis indicates that the vulnerability arises from failing to properly sanitize user input when generating web pages. This oversight allows malicious users to craft URLs that, when accessed, execute harmful scripts in the browser of unsuspecting users. The attack vector is network-based, thus any user accessing the compromised web page could be at risk. The attack complexity is low, as it does not require advanced skills or access privileges. User interaction is necessary for the exploitation to succeed, as the user must click the malicious link. The potential impacts include low confidentiality, integrity, and availability, but the consequences could still be severe depending on the exploit's context.
Risk & Impact Analysis
Risk to organizations includes the potential for data compromise and unauthorized actions performed in the context of a legitimate user. The blast radius can be extensive, especially for organizations with a significant number of users interacting with the Gallerio plugin. Given that user interaction is required for exploitation, the urgency for organizations to address this vulnerability is high, particularly for those who manage sensitive data or operate in regulated industries.
Exploitation Status
Signal | Status |
|---|---|
Known Exploit | No |
Public PoC | No |
Actively Exploited | No |
Ransomware Use | No |
Affected Versions
All versions prior to vendor patch (1.0.1) are affected by this vulnerability. Organizations must ensure that they upgrade to the latest version to mitigate risks.
Mitigation & Remediation
Organizations should address this vulnerability by applying the latest updates to the Gallerio plugin. For those unable to immediately patch, implementing input validation and sanitization measures can reduce the XSS risk. Additionally, organizations may consider engaging in penetration testing to identify potential security gaps and further enhance their defenses.
Detection Guidance
Monitoring for unusual user behavior, such as unexpected script execution or unauthorized access attempts, can help detect exploitation attempts. Additionally, organizations should review logs for anomalies that may indicate attempted XSS attacks.
