Summary

CVE-2025-14600 is an insecure deserialization / path traversal vulnerability in vsDesk, a helpdesk platform, that allows a remote, unauthenticated attacker to gain unauthorized administrative access. By manipulating application configuration data, an attacker can force the system to authenticate against an attacker-controlled LDAP server and provision a new administrative account. The flaw carries a CVSS v4.0 base score of 9.3 (Critical) and requires no privileges or user interaction to exploit.

Technical details

  • Root cause: vsDesk’s configuration file selection logic does not properly restrict which configuration file is loaded, combined with insecure deserialization of configuration data, enabling path traversal.
  • Trigger condition: an attacker manipulates application configuration data/inputs used to select or deserialize a configuration file.
  • Attack vector: Network — the vulnerability is exploitable remotely with no authentication and no user interaction (AV:N/AC:L/AT:N/PR:N/UI:N).
  • Impact: the manipulated configuration causes vsDesk to authenticate against an arbitrary, attacker-controlled LDAP server, which allows provisioning of a new administrative account, resulting in full compromise of confidentiality, integrity, and availability.

Affected software

  • vsDesk version 11.06.02
  • vsDesk version 14.01.01
  • Fixed in vsDesk version 14.0402 and later (the vendor’s 14.0422 release notes confirm the path traversal/deserialization issue was addressed by restricting configuration file selection to designated directories using basename and realpath validation)

Severity

  • CVSS v4.0 Base Score: 9.3 (Critical)
  • Vector: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N

Mitigation and recommended actions

  • Immediate: Upgrade vsDesk to version 14.0402 or later (vendor patch obtained from https://vsdesk.ru/).
  • If unable to patch immediately: restrict network access to the vsDesk administrative and configuration interfaces to trusted management networks, and monitor for unexpected LDAP authentication attempts to unrecognized external servers.
  • Review existing administrative accounts for any unauthorized or unrecognized entries created around the time of suspected exploitation.

How IONIX identifies potentially affected assets

IONIX matches the following signals against data already collected when it crawled the asset; identifying the technology sends no request beyond that crawl.

  • Named response header (set-cookie): NAVCOLLAPSE=
  • Raw HTTP response body: src=" or href=" containing /themes/vsdesk/assets/

How IONIX’s External Exposure Management Platform Detects and Validates
Zero-Days to Shrink MTTR

1

Map your entire attack surface (continously)

IONIX uses multi-factor discovery methods, including DNS analysis, certificate mapping, metadata inspection, and more, to automatically map every internet-facing asset across your environment. This includes cloud instances, third-party platforms, shadow IT, and even forgotten infrastructure that traditional tools miss.

2

Monitor for new CVEs

Dozens of threat intel feeds using agentic technology are continuously analyzed to detect the appearance of proof-of-concept code, exploit kits, and indicators of active targeting. IONIX goes further by applying AI to proactively evaluate whether emerging vulnerabilities are likely to be exploited, even before PoCs go public.

3

Identify Potential External Exposures

Not all CVEs matter. IONIX filters vulnerabilities by asking attacker-centric questions: Can it be reached from the internet? Does it require authentication? Is it being exploited in the wild? This dramatically reduces noise and focuses teams on threats that can actually be weaponized.

4

Create Safe, Scalable Exploit Validations

IONIX transforms real-world PoCs into safe, non-intrusive test payloads that can be run in production environments without disruption. These simulations are precisely targeted to the systems that are vulnerable, ensuring rapid validation without unnecessary load.

5

Execute Exploit Validations

By combining context about software stack, versioning, exposure status, and reachability, IONIX ensures that only the right payloads are executed against the right assets, maximizing efficiency and minimizing risk.

6

Drive Fast and Actionable Remediation

Results are routed through integrations with ticketing, SOAR, and SIEM tools. Issues are written in plain language, bundled into remediation clusters, and prioritized based on asset criticality, exploitability, and blast radius. This shortens mean time to remediation (MTTR) and empowers teams to act with confidence.
