CVE-2019-12693

CVE-2019-12693 is a denial-of-service vulnerability affecting Cisco Adaptive Security Appliance (ASA) Software's Secure Copy (SCP) feature. It stems from an incorrect data type used for a length variable, which can be exploited by an authenticated, remote attacker with privilege level 15 credentials. By initiating a large file transfer, the attacker can cause the variable to roll over, leading to a device crash. Rated as Medium severity (CVSS 4.9), this vulnerability requires high privileges and has a low attack complexity. There is currently no evidence of active exploitation, public exploit code (Metasploit, Nuclei, ExploitDB), or significant community discussion or media coverage.
