CVE-2025-52465: GeoServer has an arbitrary file write vulnerability in its Master Password Dump Page
GeoServer is an open source server that allows users to share and edit geospatial data. Prior to versions 2.26.4 and 2.27.3, a vulnerability exists that allows an authenticated administrator with access to GeoServer's security system to pass arbitrary file names to the Master Password Dump web page and create files containing the master password in plaintext. The provided file name must be an absolute path to the target file, the target file can not already exist and all parent directories must already exist. Versions 2.26.4 and 2.27.3 contain a fix. GeoServer installations where the web interface is either disabled or completely removed are not affected since the vulnerability exists in one of the web pages.
Security readout for executives and security teams
Plain-English summary
GeoServer administrators could make a vulnerable web page write the system master password into a new plaintext file at a chosen absolute path. This requires high privileges, but compromise or misuse of an admin account could expose sensitive secrets and affect system integrity.
Executive priority
Treat as high priority for internet-reachable or broadly administered GeoServer environments. The prerequisite is high privilege, but the exposed asset is the master password, making impact potentially severe after admin compromise.
Technical view
CVE-2025-52465 is a CWE-73 arbitrary file-name/path issue in GeoServer's Master Password Dump Page. Authenticated administrators with security-system access can supply an absolute output path, if the file does not already exist and parent directories exist. Fixed in GeoServer 2.26.4 and 2.27.3.
Likely exposure
Exposure is limited to GeoServer deployments running affected gs-web-app or gs-web-sec-core versions with the web interface enabled. Installations with the web interface disabled or removed are listed as not affected.
Exploitation context
No active exploitation is supported by the provided evidence. The CVE is not marked KEV. Abuse requires authenticated administrator access, so risk rises sharply where admin credentials, SSO, or management networks are weak.
Researcher notes
The bundled Check Point reference appears to concern CVE-2025-24054, not this GeoServer issue, so it should not be used to infer exploitation of CVE-2025-52465. Evidence is strongest from the CVE record, GitHub advisory, fix PR, and OSGeo issue.
Mitigation direction
Upgrade GeoServer to 2.26.4 or 2.27.3 or later.
Disable or remove the GeoServer web interface where operationally feasible.
Restrict GeoServer admin access to trusted networks and named administrators.
Review vendor guidance before applying compensating controls.
Rotate secrets if master password exposure is suspected.
Validation and detection
Inventory GeoServer versions and affected Maven components.
Confirm whether the GeoServer web interface is enabled.
Review administrator account access to the security system.
Check for unexpected newly created files in writable server paths.

File traversal and upload weaknesses can lead teams to review file, web shell, execution, and collection telemetry. Open the exact CWE lookup page first, then review the ATT&CK searches from that MITRE weakness context. This is a Glexia lookup hint, not an official ATT&CK mapping.
The CVE wording references authentication or credential exposure, so valid-account and credential-access review may help. This is a Glexia inferred lookup path, not an official MITRE, ATT&CK, or CVE Program mapping.
