CVE-2025-14602: Weak File Name Generation in vsDesk
The application generates uploaded file names using a weak and predictable method based on the request timestamp. This allows a remote attacker to accurately guess or brute-force the generated filename within a short time window. An attacker can successfully locate and access uploaded files, which can be used to facilitate further attacks.
Apply patch from vendor https://vsdesk.ru/ . Versions 14.0101 and on have the patch.
Security readout for executives and security teams
Plain-English summary
vsDesk may assign uploaded files names derived predictably from request timestamps. A low-privileged remote attacker could guess those names and access uploaded content, potentially exposing sensitive information or enabling follow-on attacks. The supplied record rates this medium severity, with limited confidentiality impact.
Executive priority
Prioritize remediation for externally reachable deployments handling confidential uploads. Treat this as a moderate, near-term patching item rather than an emergency, unless investigation finds sensitive-file exposure or suspicious access patterns.
Technical view
CVE-2025-14602 is a predictable filename weakness classified as CWE-340 and CWE-377. The CVSS 4.0 score is 5.3, reflecting network reachability, low complexity, low privileges, no user interaction, and limited confidentiality impact. The supplied data says 14.0101 and later are patched, but also lists 14.0101 as affected.
Likely exposure
Exposure is most likely where vsDesk permits low-privileged users to upload files and those files can be retrieved remotely by generated name. The supplied bundle identifies version 11.06.02 but contains conflicting information about whether 14.0101 is affected or fixed.
Exploitation context
The filename can reportedly be guessed or brute-forced within a short timestamp window, allowing unauthorized file discovery. The supplied sources provide no evidence of active exploitation, and the CVE is not listed as KEV in the bundle.
Researcher notes
The core issue is insufficient unpredictability in server-generated upload names. CVSS indicates privileges are required and confidentiality impact is limited. Exact affected-version boundaries require clarification: the bundle says 14.0101 and later are patched while its affected list includes 14.0101. No public exploitation evidence is supplied.
Mitigation direction
Apply the vendor patch and move to a vendor-confirmed fixed release.
Confirm 14.0101 status with the vendor because the supplied version data conflicts.
Restrict uploaded-file retrieval to explicitly authorized users where operationally possible.
Limit upload privileges and monitor suspicious repeated requests for generated files.
Validation and detection
Inventory all vsDesk deployments and record their precise versions and builds.
Obtain vendor confirmation that each deployed release contains the filename-generation patch.
Verify patched systems no longer generate predictably timestamp-based upload names.
Review access logs for repeated file requests clustered around upload timestamps.
Confirm uploaded files require appropriate authorization rather than filename knowledge alone.
