CVE-2020-3132 (GCVE-0-2020-3132)

Vulnerability from cvelistv5 – Published: 2020-02-19 19:16 – Updated: 2024-11-15 17:40

Title

Cisco Email Security Appliance Shortened URL Denial of Service Vulnerability

Summary

A vulnerability in the email message scanning feature of Cisco AsyncOS Software for Cisco Email Security Appliance (ESA) could allow an unauthenticated, remote attacker to cause a temporary denial of service (DoS) condition on an affected device. The vulnerability is due to inadequate parsing mechanisms for specific email body components. An attacker could exploit this vulnerability by sending a malicious email containing a high number of shortened URLs through an affected device. A successful exploit could allow the attacker to consume processing resources, causing a DoS condition on an affected device. To successfully exploit this vulnerability, certain conditions beyond the control of the attacker must occur.

Severity

6.8 (Medium)
