CWE-ID:
CWE-113 - Improper Neutralization of CRLF Sequences in HTTP Headers ('HTTP Response Splitting')
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to bypass security restrictions on the target system.
The weakness exists due to an error in the alpha_auth_check() function. By setting the user agent string to xmlset_roodkcableoj28840ybtide, an attacker can send an HTTP request to bypass authentication and obtain administrative access to the device.
Successful exploitation of the vulnerability results in full access to the vulnerable system.
Note: the vulnerability was being actively exploited.
