Security readout for executives and security teams
Plain-English summary
Doc2k RE-Chat 1.0 has a cross-site scripting issue in re_chat.js. A remote authenticated attacker could potentially make malicious script run in a user’s browser, affecting integrity rather than confidentiality or availability. Public sources name a patch commit, but provide limited implementation detail.
Executive priority
Treat as a moderate web-application risk. It is not supported as actively exploited, but browser-script injection can damage trust, sessions, and user workflows. Patch or retire affected deployments during normal vulnerability remediation cycles.
Technical view
CVE-2016-15035 is CWE-79 cross-site scripting affecting an unknown part of js_on_radio-emergency.de_/re_chat.js in Doc2k RE-Chat 1.0. CVSS v2 is 4.0 with network access, low complexity, and authentication required. VulDB associates it with VDB-238155 and references commit bd17d497ddd3bab4ef9c6831c747c37cc016c570 as the fix.
Likely exposure
Exposure appears limited to organizations running Doc2k RE-Chat 1.0, especially internet-accessible or externally reachable deployments. The CVSS vector requires an authenticated attacker, reducing broad opportunistic risk compared with unauthenticated XSS.
Exploitation context
The source bundle says remote attack is possible, but does not cite active exploitation. The CVE is not listed as KEV in the provided data. No public exploit status beyond the vulnerability description is supported here.
Researcher notes
The public description lacks the exact vulnerable parameter or code path, so validation should rely on version control diff review and controlled regression testing. Do not assume other Doc2k products or RE-Chat versions are affected without separate evidence.
Mitigation direction
- Apply the referenced upstream patch commit if running RE-Chat 1.0.
- Check the project or vendor repository for any later maintenance guidance.
- Restrict RE-Chat access to trusted authenticated users where possible.
- Prioritize replacement or upgrade if the project is unmaintained.
Validation and detection
- Inventory systems for Doc2k RE-Chat 1.0 deployments.
- Confirm whether re_chat.js includes commit bd17d497ddd3bab4ef9c6831c747c37cc016c570.
- Review exposed RE-Chat instances and authentication boundaries.
- Run safe XSS regression testing in a controlled environment.

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.
