Published: 11 April 2024
Summary
CVE-2024-25852 is a high-severity Improper Access Control (CWE-284) vulnerability in Linksys Re7000 Firmware. Its CVSS base score is 8.8 (High).
Operationally, ranked in the top 0.2% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.
Deeper analysis
Linksys RE7000 firmware versions 2.0.9, 2.0.11, and 2.0.15 contain a command execution vulnerability in the AccessControlList parameter of the access control function. The flaw is tracked as CVE-2024-25852, carries a CVSS 3.1 score of 8.8, and is associated with CWE-284 improper access control.
An attacker positioned on the adjacent network can submit a crafted value to the affected parameter without authentication or user interaction, resulting in arbitrary command execution that yields full device administrator privileges. The current EPSS score of 0.9305, with a recorded peak of 0.9325, indicates a high likelihood of exploitation attempts.
Public references consist of technical write-ups on GitHub and Notion that document the issue but contain no vendor statements on patches or mitigation steps.

Likely Mitigating Controls AI
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.
The access control policy and procedures directly mandate and enforce proper access control mechanisms across the organization.
Device lock enforces restricted access until re-authentication, directly reducing unauthorized use of active sessions.
Supervision and review of access control activities directly detects and remediates improper access configurations or usages.
Explicitly identifying and documenting actions permitted without identification or authentication enforces proper access control boundaries by defining justified exceptions.
By automatically labeling outputs with security attributes, the control supports attribute-based enforcement and reduces exploitability of improper access control weaknesses.
Associating and retaining security attributes with data directly supports enforcement of access control decisions across storage, processing, and transmission.
Requiring prior authorization for each remote access type prevents improper access control over remote connections.
Requiring authorization of wireless access before allowing connections enforces proper access control for this access method.
