CVE-2024-29014: 
SonicWall NetExtender vulnerability analysis and mitigation

A high-severity vulnerability (CVE-2024-29014) affects SonicWall SMA100 NetExtender Windows (32 and 64-bit) client version 10.2.339 and earlier versions. The vulnerability allows attackers to execute arbitrary code when processing an End Point Control (EPC) Client update. This security flaw was discovered and disclosed in July 2024 (SonicWall Advisory).

The vulnerability has been assigned a CVSS v3.1 base score of 7.1 (High) with the vector string CVSS:3.1/AV:N/AC:H/PR:L/UI:R/S:U/C:H/I:H/A:H according to CISA-ADP. The flaw stems from insufficient signature validation in the update process. The vulnerability is classified as CWE-94 (Improper Control of Generation of Code) (NVD).

When successfully exploited, the vulnerability allows attackers to execute code with SYSTEM privileges on affected Windows systems. This high-privilege access could potentially lead to complete system compromise (Hacker News).

SonicWall has released patches to address this vulnerability in NetExtender Windows (32 and 64 bit) version 10.2.341 and later versions. If immediate upgrade is not possible, organizations are advised to use a client firewall to restrict access to known, legitimate VPN endpoints to prevent users from inadvertently connecting to malicious servers (SecurityWeek).
