Security Advisory Description
A vulnerability was found in libssh, where the authentication check of the connecting client can be bypassed in thepki_verify_data_signature
function in memory allocation problems. This issue may happen if there is insufficient memory or the memory usage is limited. The problem is caused by the return value rc,
which is initialized to SSH_ERROR and later rewritten to save the return value of the function call pki_key_check_hash_compatible.
The value of the variable is not changed between this point and the cryptographic verification. Therefore any error between them calls goto error
returning SSH_OK. (CVE-2023-2283)
Impact
BIG-IP AFM
This vulnerability could allow an attacker, under certain conditions, to establish an SSH Proxy session when it should have been denied.
BIG-IP Next SPK, BIG-IP Next CNF, and Traffix SDC
This vulnerability could allow an attacker, under certain conditions, to establish an SSH session when it should have been denied.
