A vulnerability in code that handles privilege assignment when the
Cisco ASA device is accessed using the Cisco ASDM could allow an authenticated, remote
attacker to elevate privileges and gain administrative access to the affected
The vulnerability is due to improper privilege assignment
to users with privilege level 0. An attacker could exploit this
vulnerability by logging in to the Cisco ASDM with user credentials with
privilege level 0. An exploit could allow the attacker or an unprivileged user
to elevate the access privileges and gain administrative access to the affected
Cisco has confirmed the vulnerability in a security advisory and released software updates.
Indicators of Compromise
The following Cisco ASA Software versions are affected:
Cisco ASA Software versions prior to 8.2(5.47)
Cisco ASA Software versions prior to 8.4(7.5)
Cisco ASA Software versions prior to 8.7(1.11)
Cisco ASA Software versions prior to 9.0(3.10)
Cisco ASA Software versions prior to 9.1(3.4)
The vulnerability is due to an improper privilege assignment to a user with privilege level 0.
An attacker could exploit this vulnerability by logging in to the Cisco ASDM with user credential with privilege 0. If successful, the attacker could have the ability to escalate the access privileges and gain administrative access to the affected system, which could result in a complete system compromise.
To exploit this vulnerability, an attacker must first authenticate to the targeted device via the Cisco ASDM. This access requirement decreases the likelihood of a successful exploit.
Cisco indicates through the CVSS score that functional exploit code exists; however, the code is not known to be publicly available.
