Overview
This article details a Stored Cross-Site Scripting (XSS) vulnerability identified as CVE-2025-62295 affecting SOPlanning, a web-based scheduling application. This vulnerability resides in the /groupe_form endpoint and could allow a malicious attacker with medium privileges to inject arbitrary HTML and JavaScript into the website. This injected code will be rendered/executed when another user opens the editor within SOPlanning. Users of SOPlanning are strongly advised to upgrade to version 1.55 to mitigate this risk.
Technical Details
CVE-2025-62295 is a Stored XSS vulnerability. This means that malicious JavaScript code can be permanently injected into the SOPlanning application’s database. Specifically, the /groupe_form endpoint is vulnerable. An attacker with medium privileges (e.g., a user with group creation or editing permissions) can inject malicious code through a form field that lacks proper input sanitization. This injected code will then be executed in the browser of any user who accesses the affected group editing page.
CVSS Analysis
Currently, the CVSS score is N/A. While the vulnerability exists, the specific CVSS score and severity assessment are pending/unavailable at this time of publishing. Despite the lack of a score, it is strongly recommended to patch immediately as XSS vulnerabilities can lead to serious compromise.
Possible Impact
A successful XSS attack can have significant consequences, including:
- Session Hijacking: Attackers can steal user session cookies, gaining unauthorized access to accounts.
- Data Theft: Sensitive data displayed within the SOPlanning application (e.g., employee information, schedules, client data) can be stolen.
- Malware Distribution: The injected script can redirect users to malicious websites or attempt to download and install malware.
- Defacement: The application’s appearance can be altered to display misleading or harmful information.
- Privilege Escalation: In some cases, XSS can be used to escalate privileges within the application.
Mitigation or Patch Steps
The vulnerability has been patched in SOPlanning version 1.55. To mitigate the risk, users should:
- Upgrade to Version 1.55: Download and install the latest version of SOPlanning from the official website.
- Review User Permissions: Ensure that user accounts have appropriate levels of access. Restrict group creation/editing privileges to trusted personnel only.
- Web Application Firewall (WAF): Implement a WAF to filter malicious requests and potentially block XSS attempts.
