CVE-2018-0315: A vulnerability in the authentication, authorization, and accounting (AAA) security services of Cisco IOS X...

A vulnerability in the authentication, authorization, and accounting (AAA) security services of Cisco IOS XE Software could allow an unauthenticated, remote attacker to execute arbitrary code on an affected device or cause an affected device to reload, resulting in a denial of service (DoS) condition. The vulnerability is due to incorrect memory operations that the affected software performs when the software parses a username during login authentication. An attacker could exploit this vulnerability by attempting to authenticate to an affected device. A successful exploit could allow the attacker to execute arbitrary code on the affected device or cause the affected device to reload, resulting in a DoS condition. This vulnerability affects Cisco devices that are running Cisco IOS XE Software Release Fuji 16.7.1 or Fuji 16.8.1 and are configured to use AAA for login authentication. Cisco Bug IDs: CSCvi25380.

Security readout for executives and security teams

This flaw affects specific Cisco IOS XE Fuji releases when AAA is used for login authentication. A remote unauthenticated attacker attempting login could crash the device or execute arbitrary code. For executives, the concern is disruption or compromise of network infrastructure, but exposure is limited to the named versions and configuration. Likely exposed assets are Cisco devices running IOS XE Fuji 16.7.1 or Fuji 16.8.1 with AAA enabled for login authentication. The provided bundle does not identify other affected releases, device models, or CPEs. Treat as high priority where affected Cisco IOS XE devices support critical network paths or exposed administration interfaces. The business risk is infrastructure outage or device compromise, but confirmation requires version and AAA configuration checks. Mitigation focus: Check Cisco advisory for fixed software and supported upgrade guidance.; Prioritize remediation for affected devices reachable from untrusted networks.; Limit management and login access to trusted administration paths..

Improper Restriction of Operations within the Bounds of a Memory Buffer

Improper Restriction of Operations within the Bounds of a Memory Buffer represents a recurring weakness pattern that can create exploitable paths when design, validation, or implementation controls are missing.
