Adminer versions 5.3.0 through 5.4.2 with the sql-log plugin enabled contain an arbitrary file write vulnerability in the ns parameter of plugins/sql-log.php. An authenticated user can supply path traversal sequences in the ns parameter to write arbitrary .sql files with attacker-controlled content to any writable directory on the host.
AnalysisAI
Arbitrary file write in Adminer 5.3.0-5.4.2 allows any authenticated user to write attacker-controlled content to arbitrary writable filesystem paths via path traversal in the ns parameter of the sql-log plugin. The written files are constrained to a .sql extension, which limits but does not eliminate the integrity impact - an attacker can overwrite existing .sql files, pollute backup directories, or write large files to fill disk. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires three simultaneous conditions: (1) the attacker must be authenticated to the Adminer instance - any valid database user credential satisfies this, as Adminer authenticates directly via database credentials; (2) the sql-log plugin must be explicitly enabled in the Adminer deployment, which is not the default configuration; (3) the web server process must have write permissions to the target directory chosen via path traversal. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 4.0 score of 5.3 (Medium) reflects the bounded real-world impact: authentication is required (PR:L), the sql-log plugin must be explicitly enabled (non-default), and the writable file type is constrained to .sql. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | Full exploit scenario with step-by-step reproduction available after sign-in. |
| Remediation | Upgrade Adminer to a version beyond 5.4.2 once a patched release is confirmed via the vendor advisory at https://github.com/vrana/adminer/security/advisories/GHSA-75xm-qwfq-9wp5 - the exact fixed version is not independently confirmed from the available input data, so verify against the advisory before deploying. … Detailed patch versions, workarounds, and compensating controls in full report. |
