SonicWall Issues Patches for a New Critical Flaw in SMA 100 Series Devices

Community stability firm SonicWall has dealt with a important stability vulnerability affecting its Safe Cell Entry (SMA) 100 series appliances that can allow distant, unauthenticated attackers to achieve administrator entry on qualified gadgets remotely.

Tracked as CVE-2021-20034, the arbitrary file deletion flaw is rated 9.1 out of a highest of 10 on the CVSS scoring method, and could allow for an adversary to bypass path traversal checks and delete any file, causing the gadgets to reboot to manufacturing unit default settings.

“The vulnerability is thanks to an improper limitation of a file route to a limited listing potentially primary to arbitrary file deletion as ‘nobody,”” the San Jose-centered organization observed in an advisory released Thursday. “There is no evidence that this vulnerability is staying exploited in the wild.”

SonicWall credited Wenxu Yin of Alpha Lab, Qihoo 360, with reporting the safety shortcoming, which impacts SMA 100 Series — SMA 200, SMA 210, SMA 400, SMA 410, and SMA 500v — working the adhering to versions:

  • 9…10-28sv and earlier
