Security readout for executives and security teams
Plain-English summary
CVE-2019-25262 is a cross-site scripting issue in the Razgover chat message handler. A user with access to send chat messages could cause script content to be handled unsafely through the msg parameter. Business impact is mainly user/session risk inside deployments of this unsupported project, not server takeover based on the provided data.
Executive priority
Address during the next normal vulnerability remediation cycle unless Razgover is internet-facing or used by untrusted users. Priority increases if the chat service supports sensitive users, administrative sessions, or public registration. Unsupported software status is the main business concern.
Technical view
The issue affects elinicksic Razgover up to commit db37dfc5c82f023a40f2f7834ded6633fb2b5262, in Chattify/send.php. Manipulation of the msg argument leads to cross-site scripting. The CVSS 4.0 score is 5.1, with network access, low attack complexity, low privileges required, and user interaction required. A patch commit is identified as 995dd89d0e3ec5522966724be23a5d58ca1bdac3.
Likely exposure
Exposure is limited to organizations running elinicksic Razgover, especially code at or before the affected commit. The source states the product used rolling releases, so fixed and affected version numbers are not disclosed. It also states the affected product is no longer supported by the maintainer.
Exploitation context
The vulnerability is remotely reachable but requires low privileges and user interaction per the CVSS vector. The provided sources do not show CISA KEV listing or active exploitation. Treat it as plausible in exposed chat deployments, but do not assume exploitation without local evidence.
Researcher notes
Evidence is limited to the CVE record, VulDB entry, and GitHub patch reference. The vulnerability is described as XSS in msg within send.php. No affected release numbers are provided because the project uses rolling releases. No public source in the bundle confirms active exploitation.
Mitigation direction
- Apply patch commit 995dd89d0e3ec5522966724be23a5d58ca1bdac3 if maintaining this codebase.
- If unable to patch, restrict access to trusted users only.
- Review vendor/project guidance because the source says the affected product is unsupported.
- Consider replacing unsupported Razgover deployments with a maintained alternative.
Validation and detection
- Inventory applications for elinicksic Razgover or copied Chattify/send.php code.
- Check deployed code commit against db37dfc5c82f023a40f2f7834ded6633fb2b5262 and the patch commit.
- Review chat message rendering for proper output encoding of message content.
- Inspect logs for unusual chat messages and suspicious user-session activity.
