AlienVault OTX Vulnerabilities

AlienVault OTX Malware

EDK2's Network Package is susceptible to an infinite loop vulnerability when parsing unknown options in the Destination Options header of IPv6. This
 vulnerability can be exploited by an attacker to gain unauthorized 
access and potentially lead to a loss of Availability.

CVE-2023-45232 is a vulnerability classified under CWE-835 (Loop with Unreachable Exit Condition) found in the TianoCore edk2 project, which is an open-source implementation of the UEFI firmware. The flaw exists in the Network Package component responsible for parsing IPv6 packets, specifically the Destination Options header. When the parser encounters unknown options within this header, it can enter an infinite loop due to a missing or incorrect exit condition in the code. This infinite loop causes the firmware to hang, effectively leading to a denial-of-service (DoS) condition at the firmware level. The vulnerability is remotely exploitable without requiring any privileges or user interaction, as it can be triggered by sending crafted IPv6 packets to the affected system. The CVSS v3.1 score of 7.5 reflects the high severity, emphasizing the ease of remote exploitation and the impact on availability. Although no public exploits have been reported yet, the potential for disruption is significant, especially in environments where edk2-based firmware is widely deployed. The affected version is edk2-stable202308, and no official patches have been linked yet, indicating that mitigation may currently rely on workarounds or network-level protections. This vulnerability is particularly critical because firmware-level DoS can prevent systems from booting or cause persistent instability, impacting operational continuity.
