Overview
This article details a Stored Cross-Site Scripting (XSS) vulnerability, identified as CVE-2025-62296, affecting SOPlanning, a web-based scheduling and resource management application. The vulnerability resides within the /taches endpoint, allowing attackers with medium privileges to inject malicious HTML and JavaScript code into the application. This injected code is then executed whenever a user opens the affected editor within SOPlanning.
Technical Details
CVE-2025-62296 is a Stored XSS vulnerability. This means the malicious payload is permanently stored on the server (in the SOPlanning database in this case) and executed when other users interact with the compromised data. In this specific instance, an attacker with sufficient (medium) privileges can inject malicious code via the /taches endpoint. When a user opens the editor related to the task (tache), the injected JavaScript code is executed within their browser. This code can then perform actions such as stealing cookies, redirecting the user to a phishing site, or even modifying data within the SOPlanning application itself.
CVSS Analysis
As of the publication date, a CVSS score has not been assigned to CVE-2025-62296. Due to the nature of Stored XSS, its potential impact can range from information disclosure to complete account takeover. A CVSS score would typically consider factors like attack complexity, user interaction required, and the scope of impact when determining the severity.
Possible Impact
The exploitation of CVE-2025-62296 can have serious consequences:
- Account Compromise: An attacker could steal user session cookies and hijack user accounts, gaining unauthorized access to sensitive information.
- Data Manipulation: Injected JavaScript code could be used to modify or delete data within SOPlanning, leading to data corruption or loss.
- Phishing Attacks: The attacker could redirect users to malicious websites designed to steal their credentials or install malware.
- Website Defacement: The injected code could alter the appearance and functionality of the SOPlanning application.
Mitigation and Patch Steps
The vulnerability (CVE-2025-62296) has been fixed in SOPlanning version 1.55. It is strongly recommended that all SOPlanning users upgrade to version 1.55 or later as soon as possible. The upgrade addresses the insufficient input validation and output encoding at the /taches endpoint which was exploited to inject malicious scripts.
Steps to mitigate the risk before upgrading:
- Review user access privileges and restrict access to the
/tachesendpoint to only trusted users. - Monitor SOPlanning logs for suspicious activity, such as unusual requests or modifications to tasks.
- Implement a Web Application Firewall (WAF) to filter out potentially malicious requests.
