Default Credentials and Arbitrary File Read in Hikvision Streaming Media Management Server v2.3.5

IdentifiersCVE-2025-34058CWE-798

CVE-2025-34058 affects Hikvision Streaming Media Management Server v2.3.5. The product uses default credentials that permit remote attackers to authenticate to the application and access restricted functionality. Once authenticated, an attacker can exploit an arbitrary file read issue in the /systemLog/downFile.php endpoint by supplying directory traversal sequences in the fileName parameter, allowing retrieval of files outside the intended directory. The issue is therefore an exploit chain combining the use of default credentials with a path traversal-based arbitrary file read, resulting in unauthorized access to sensitive system files.

ANALYST BRIEF

Impact, mitigation & remediation

What it means. What to do now. Patch path, mitigations, and the assume-compromise checklist.

Impact

What an attacker gets, and what they’ve been doing with it.

Successful exploitation allows a remote attacker to log in with default credentials, bypass intended access restrictions, and read arbitrary files accessible to the application through directory traversal in /systemLog/downFile.php. This can expose sensitive system files and application data, potentially including configuration files, credentials, logs, and other information useful for further compromise.

Mitigation

If you can’t patch tonight, do this now.

If an official fix is not yet available, restrict network access to the management interface to trusted administrative hosts or a VPN, disable or remove default accounts, enforce strong unique passwords, and monitor for authentication using known default credentials. As a compensating control, block or filter requests to /systemLog/downFile.php where the fileName parameter contains traversal patterns, and use a reverse proxy or WAF to detect and deny such requests. Minimize the application's filesystem permissions to reduce the impact of arbitrary file reads.

Remediation

Patch, then assume compromise.

Change or disable all default credentials immediately and ensure no default or hardcoded administrative accounts remain usable in production deployments. Upgrade to a vendor-fixed version if one is available. In addition, remediate the arbitrary file read flaw in /systemLog/downFile.php by validating and canonicalizing the fileName parameter, restricting access to an allowlisted directory, and rejecting traversal sequences. Review exposed files and credentials for possible compromise and rotate any secrets that may have been disclosed.
