Lifecycle Timeline
7DescriptionCVE.org
A security flaw has been discovered in BichitroGan ISP Billing Software 2025.3.20. This impacts an unknown function of the file /?_route=settings/users-view/ of the component Profile Page Handler. Performing a manipulation results in cross site scripting. The attack is possible to be carried out remotely. The vendor was contacted early about this disclosure but did not respond in any way.
AnalysisAI
Stored cross-site scripting (XSS) in BichitroGan ISP Billing Software 2025.3.20 allows authenticated high-privilege users to inject malicious scripts via the Profile Page Handler settings/users-view endpoint, affecting subsequent users who view the compromised profile. The vulnerability requires high-privilege authentication and user interaction (page viewing), limiting exploitation scope; however, publicly available proof-of-concept code exists and the vendor has not responded to disclosure attempts.

Vulnerability AssessmentAI
| Exploitation | High-privilege user account authentication is required (PR:H indicates privilege level requirement). … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | Real-world risk is LOW to MODERATE despite the publicly available exploit code. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker with high-privilege administrative credentials (either obtained through credential compromise or as an insider) navigates to /?_route=settings/users-view/ and injects malicious JavaScript into a user profile field (e.g., display name, email, phone). When another administrator or authorized user views the compromised profile page, the injected script executes in their browser, potentially stealing session cookies, redirecting them to a phishing site, or performing unauthorized actions within the billing system. |
| Remediation | The primary remediation is to upgrade BichitroGan ISP Billing Software to a patched version; however, no patched version has been identified in available data, and the vendor has not responded to disclosure. … Detailed patch versions, workarounds, and compensating controls in full report. |
