Summary

CVE-2025-34058 is a high-severity Path Traversal (CWE-22) vulnerability in Csdn (inferred from references). Its CVSS base score is 8.7 (High).

Operationally, ranked in the top 13.4% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.

Deeper analysis

Hikvision Streaming Media Management Server version 2.3.5 is affected by a pair of weaknesses that together permit remote access to sensitive files. The product ships with default credentials that satisfy authentication checks, after which an arbitrary file read flaw in the /systemLog/downFile.php endpoint can be triggered by supplying directory-traversal sequences in the fileName parameter. The issues are tracked as CWE-22 and CWE-521 and carry a CVSS 4.0 score of 8.7 reflecting network attackability without required credentials or user interaction.

An unauthenticated remote attacker can first log in using the documented defaults and then retrieve arbitrary system files by manipulating the fileName value. Successful exploitation yields disclosure of configuration data, logs, or other restricted content stored on the server, without the need for additional privileges or local access.

Public references point to Hikvision’s security advisory page, a CNVD entry, and independent analyses that document the default-credential and path-traversal chain. The associated EPSS score remains flat at 0.0286 with no material increase since disclosure.

Vulnerability details

Hikvision Streaming Media Management Server v2.3.5 uses default credentials that allow remote attackers to authenticate and access restricted functionality. After authenticating with these credentials, an attacker can exploit an arbitrary file read vulnerability in the /systemLog/downFile.php endpoint via directory traversal…
