CVE-2025-34068
Published: 15 July 2025
Summary
CVE-2025-34068 is a critical-severity Missing Authentication for Critical Function (CWE-306) vulnerability in Medium (inferred from references). Its CVSS base score is 9.3 (Critical).
Operationally, ranked in the top 12.4% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.
Deeper analysis
An unauthenticated remote command execution vulnerability affects the Samsung WLAN AP WEA453e access point in firmware versions prior to 5.2.4.T1. The flaw stems from improper input validation in the Tech Support diagnostic feature, where the command1 and command2 parameters—accepted via POST or GET requests—allow arbitrary shell commands to be executed with root privileges on the underlying operating system.
An attacker with network access can exploit the issue without authentication by submitting crafted requests that inject commands, write output files to writable directories, and retrieve the results through a download endpoint. This grants complete device compromise, including the ability to run any root-level operation on the access point.
Exploitation evidence was recorded by the Shadowserver Foundation on 2025-02-04 UTC, predating the CVE publication date. The EPSS score remains flat at a peak of 0.0337 with no material increase. Public references, including the Samsung product support page and the Vulncheck advisory, point to upgrading to firmware 5.2.4.T1 or later as the primary remediation.

Per-CVE control mapping for this CVE has not run yet; the list below is derived from the weakness types (CWEs) cited in the NVD entry.
Requires established identification and authentication to unlock, mitigating missing authentication for continued system access.
Requiring identification and rationale for actions allowed without authentication ensures critical functions are not left unprotected by forcing review of authentication requirements.
Authorizing mobile device connections to organizational systems ensures authentication is performed for this critical access function.
Guarantees critical functions are protected by mandatory invocation of the access control mechanism.
Auditing sessions makes it possible to detect access to critical functions without required authentication.
The assessment process confirms authentication is present and effective for critical functions, preventing exploitation from missing authentication.
Certification assesses that critical functions have required authentication controls in place.
Disabling non-essential functions and services eliminates the need to secure them, reducing exposure from missing authentication on unnecessary components.
