A vulnerability in the configuration of the Pluggable Authentication Module (PAM) used in Cisco Firepower Threat Defense (FTD) Software, Cisco Firepower Management Center (FMC) Software, and Cisco FXOS Software could allow an authenticated, remote attacker to cause a denial of service (DoS) condition. The vulnerability is due to improper resource management in the context of user session management. An attacker could exploit this vulnerability by connecting to an affected system and performing many simultaneous successful Secure Shell (SSH) logins. A successful exploit could allow the attacker to exhaust system resources and cause the device to reload, resulting in a DoS condition. To exploit this vulnerability, the attacker needs valid user credentials on the system.

According to its self-reported version, Cisco FXOS Software is affected by a vulnerability in the configuration of the Pluggable Authentication Module (PAM) due to improper resource management in the context of user session management. An authenticated, remote attacker can exploit this, by connecting to an affected system and performing many simultaneous successful Secure Shell (SSH) logins, in order to exhaust system resources and cause a denial of service (DoS) condition.
