CVE-2010-1579

Description

Unspecified vulnerability in the SunRPC inspection feature on Cisco Adaptive Security Appliances (ASA) 5500 series devices with software 7.2 before 7.2(5), 8.0 before 8.0(5.19), 8.1 before 8.1(2.47), and 8.2 before 8.2(2) and Cisco PIX Security Appliances 500 series devices allows remote attackers to cause a denial of service (device reload) via crafted SunRPC UDP packets, aka Bug ID CSCtc79922.

AI Insight

LLM-synthesized narrative grounded in this CVE's description and references.

Crafted SunRPC UDP packets cause a denial of service (reload) on Cisco ASA and PIX devices running specific software versions before fixed releases.

Vulnerability

An unspecified vulnerability in the SunRPC inspection feature of Cisco Adaptive Security Appliances (ASA) 5500 series and PIX 500 series devices allows a denial of service via crafted SunRPC UDP packets. Affected software versions are ASA 7.2 before 7.2(5), 8.0 before 8.0(5.19), 8.1 before 8.1(2.47), and 8.2 before 8.2(2). This is tracked as Bug ID CSCtc79922 [1].

Exploitation

An unauthenticated remote attacker can send specially crafted SunRPC UDP packets to a vulnerable device. No special network position or credentials are required; the attack is over the network and does not require user interaction [1].

Impact

Successful exploitation causes the affected device to reload, resulting in a denial of service (DoS). This disrupts all traffic passing through the device until it reboots [1].

Mitigation

Cisco has released fixed software versions: 7.2(5), 8.0(5.19), 8.1(2.47), and 8.2(2) for ASA and corresponding PIX updates. No workarounds were provided in the advisory. The vulnerability is not listed on the CISA KEV as of the publication date [1].
