A public proof-of-concept exists for this authentication bypass flaw and reports of exploitation attempts have been observed. Immediate patching is recommended

Exploit details have been released for this authentication bypass vulnerability. Immediate patching is recommended

SonicWall has reportedly warned that this vulnerability could be exploited. Immediate patching is recommended

SonicWall SonicOS SSLVPN versions 7.1.1-7040 prior to 7.1.3-7015 and version 7.1.2-7019 are vulnerable to authentication bypass via a specially forged request that allows to hijack active SSL VPN sessions and gain unauthorized network access.

According to its self-reported version, the remote SonicWall firewall is running a version of SonicOS that is affected by multiple vulnerabilities:

  - Use of Cryptographically Weak Pseudo-Random Number Generator (PRNG) in the SonicOS SSLVPN authentication     token generator that, in certain cases, can be predicted by an attacker potentially resulting in     authentication bypass. (CVE-2024-40762)

  - An Improper Authentication vulnerability in the SSLVPN authentication mechanism allows a remote attacker     to bypass authentication. (CVE-2024-53704)

  - A Server-Side Request Forgery vulnerability in the SonicOS SSH management interface allows a remote     attacker to establish a TCP connection to an IP address on any port when the user is logged in to the firewall. (CVE-2024-53705)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.
