| Vector | AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:H/A:N |
Name of the Vulnerable Software and Affected Versions
Ubiquiti airFiber AF2X Radio versions 3.2.2 and earlier
Description
The issue is related to the use of the cyclic redundancy check (CRC) algorithm for integrity checks during firmware updates, which can be exploited by an attacker to conduct a man-in-the-middle (MITM) attack. This allows the attacker to modify the new firmware image and bypass the checksum verification. The estimated number of potentially affected devices worldwide is not specified. There is no information provided about real-world incidents where this issue was exploited.
Recommendations
For Ubiquiti airFiber AF2X Radio versions 3.2.2 and earlier, update the firmware to a version later than 3.2.2 to resolve the issue. As a temporary workaround, consider restricting access to the firmware update process to minimize the risk of exploitation. Avoid using the CRC algorithm for integrity checks during firmware updates until the issue is resolved. At the moment, there is no additional information about other mitigation measures.
