TITLE

Cisco Email Security Appliance Input validation vulnerability

Trust: 0.8

sources: JVNDB: JVNDB-2018-013703

DESCRIPTION

A vulnerability in the Secure/Multipurpose Internet Mail Extensions (S/MIME) Decryption and Verification or S/MIME Public Key Harvesting features of Cisco AsyncOS Software for Cisco Email Security Appliance (ESA) could allow an unauthenticated, remote attacker to cause an affected device to corrupt system memory. A successful exploit could cause the filtering process to unexpectedly reload, resulting in a denial of service (DoS) condition on the device. The vulnerability is due to improper input validation of S/MIME-signed emails. An attacker could exploit this vulnerability by sending a malicious S/MIME-signed email through a targeted device. If Decryption and Verification or Public Key Harvesting is configured, the filtering process could crash due to memory corruption and restart, resulting in a DoS condition. The software could then resume processing the same S/MIME-signed email, causing the filtering process to crash and restart again. A successful exploit could allow the attacker to cause a permanent DoS condition. This vulnerability may require manual intervention to recover the ESA. Cisco Email Security Appliance (ESA) Contains an input validation vulnerability.Service operation interruption (DoS) There is a possibility of being put into a state. AsyncOSSoftware is the operating system used in it. The vulnerability stems from the failure of the program to properly validate the S/MIME signed message. This issue is being tracked by Cisco Bug ID CSCvk73786. AsyncOS Software is a set of operating systems running on it. input verification
