Security readout for executives and security teams
Plain-English summary
CVE-2023-44915 is a high-severity cross-site scripting issue in c3crm up to v3.0.4. A crafted value in the login_error parameter on /Login.php can cause attacker-controlled script or HTML to run in a user’s browser. The sources do not name a vendor patch or fixed version.
Executive priority
Treat this as a near-term web application remediation item if c3crm is deployed. The business risk is credential or session exposure through browser-executed script, but urgency depends on whether the login page is reachable and actively used.
Technical view
The issue is CWE-79 reflected XSS in /Login.php, involving unsafely handled login_error input. CVSS 3.1 is 7.1: network exploitable, low complexity, no privileges required, user interaction required, with high confidentiality impact, low integrity impact, and no availability impact.
Likely exposure
Exposure is limited to organizations running c3crm up to v3.0.4 with /Login.php reachable by users or the internet. The source metadata lists affected vendor and product as n/a, so asset identification may require repository or application-name matching.
Exploitation context
The CVE record does not report CISA KEV listing, and the provided sources do not establish active exploitation. A public researcher reference exists, but this assessment does not rely on or repeat exploit mechanics.
Researcher notes
Evidence is concise and incomplete: the CVE describes the vulnerable component and parameter, with CVSS and CWE-79, but affected CPEs, vendor advisory, fixed version, and official mitigation are not provided in the bundle.
Mitigation direction
- Check upstream c3crm guidance for a fixed release or official patch.
- Restrict public access to affected login pages where business allows.
- Review /Login.php handling of login_error for safe output encoding.
- Add server-side validation for unexpected login_error content.
- Monitor web logs for suspicious login_error usage.
Validation and detection
- Inventory systems for c3crm deployments and version evidence.
- Confirm whether /Login.php is externally reachable.
- Inspect login_error rendering for unencoded user-controlled output.
- Review dependency or repository history for any security fix.
- Check security telemetry for abnormal requests to /Login.php.

Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')
Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') represents a recurring weakness pattern that can create exploitable paths when design, validation, or implementation controls are missing.
