Improper Neutralization of Input During Web Page Generation (XSS or 'Cross-site Scripting') vulnerability in Proliz Software Ltd. Co. OBS (Student Affairs Information System) allows Stored XSS.
This issue affects OBS (Student Affairs Information System): before 25.0401.
Security readout for executives and security teams
Plain-English summary
Proliz OBS has a stored cross-site scripting flaw before version 25.0401. A low-privileged user could save malicious content that later runs in another user’s browser, potentially affecting confidentiality and integrity in student affairs workflows.
Executive priority
Treat as high priority for affected OBS deployments because stored XSS can compromise trusted user sessions and student affairs data workflows, but current sources do not prove active exploitation.
Technical view
CVE-2025-11956 is CWE-79 stored XSS in Proliz Software Ltd. Co. OBS before 25.0401. CVSS 3.1 score is 8.9: network reachable, low complexity, low privileges required, user interaction required, scope changed, with high confidentiality and integrity impact.
Likely exposure
Exposure is limited to organizations running Proliz OBS Student Affairs Information System versions before 25.0401, especially where authenticated users can submit content rendered to other users.
Exploitation context
The provided sources do not show CISA KEV listing or confirmed active exploitation. The CVSS vector indicates exploitation requires low privileges and a separate user interaction event.
Researcher notes
Evidence is concise: affected product, version boundary, CWE, and CVSS are available. The bundle does not include technical root cause, vulnerable endpoints, proof-of-concept details, or detailed vendor remediation steps.
Mitigation direction
Confirm whether OBS is older than 25.0401.
Upgrade to 25.0401 or later if vendor guidance supports that.
Review the Turkish government advisory for vendor-specific instructions.
Limit OBS access to trusted networks where feasible.
Reduce unnecessary low-privileged accounts and permissions.
Monitor for suspicious stored content and unexpected script execution reports.
Validation and detection
Inventory all Proliz OBS deployments and record exact versions.
Confirm whether any instance is before 25.0401.
Review user-editable fields that render content to other users.
Use non-destructive XSS checks in staging or an approved test window.
Review logs for unusual content updates before administrator sessions.

CWE-79: User-session and phishing behavior lookup
Client-side and session-facing weaknesses should be reviewed alongside initial-access and user-execution behaviors. Open the exact CWE lookup page first, then review the ATT&CK searches from that MITRE weakness context. This is a Glexia lookup hint, not an official ATT&CK mapping.
These fields come from the CVE record and ADP containers, not from Glexia's Take. They preserve time-varying source decisions such as CISA SSVC, KEV status, CVSS metrics, and provider references.
We collect every scored CVSS vector available in the official CNA and ADP containers. When more than one version is present, the table keeps the source vectors side by side instead of collapsing them into the highest score.
