Overview<\/strong><\/p>\n

This report discusses the vulnerability identified as CVE-2023-33112, a significant security flaw affecting WLAN firmware. This vulnerability is triggered when the firmware receives a “reassoc response” frame that includes a RIC_DATA element, leading to a transient Denial of Service (DOS). Cybersecurity professionals, WLAN firmware manufacturers, and organizations that rely on wireless networks should be aware of this vulnerability due to the potential system compromise or data leakage.<\/p>\n

Vulnerability Summary<\/strong><\/p>\n

CVE ID: CVE-2023-33112
\nSeverity: High (CVSS 7.5)
\nAttack Vector: Network
\nPrivileges Required: Low
\nUser Interaction: None
\nImpact: Potential system compromise or data leakage<\/p>\n

Affected Products<\/strong><\/p>\n

Product | Affected Versions<\/p>\n

WLAN Firmware | All prior versions to patch<\/p>\n

How the Exploit Works<\/strong><\/p>\n

The exploit works by an attacker sending a “reassoc response” frame including a maliciously crafted RIC_DATA element to the target WLAN firmware. When the firmware attempts to process this frame, it leads to a transient DOS condition, causing system instability or temporary unavailability. This condition might allow a skilled attacker to compromise the system or leak sensitive data.<\/p>\n

Conceptual Example Code<\/strong><\/p>\n

While the specific details of exploiting this vulnerability are not public, a conceptual example might look something like this:<\/p>\n

# Send a maliciously crafted \"reassoc response\" frame to the target\necho -e \"\\x00\\x00\\x00\\x00\\x00\\x00\\x00\\x00\\x00\\x00\\x00\\x00\\x00\\x00\\x00\\x00\\x00\\x00\\x00\\x00\" | nc -u target.example.com 12345<\/code><\/pre>\n
This command uses echo to send a binary string (representing a malformed “reassoc response” frame) to the target system over UDP (port 12345). Note that this is a conceptual example and the real-world exploit would likely require a more sophisticated approach.<\/p>\n","protected":false},"excerpt":{"rendered":"
