CVE-2024-20268
CVSS v3.1
7.7
High
| Vector | AV:N/AC:L/PR:L/UI:N/S:C/C:N/I:N/A:H |
Name of the Vulnerable Software and Affected Versions:
Cisco Adaptive Security Appliance (ASA) Software (affected versions not specified)
Cisco Firepower Threat Defense (FTD) Software (affected versions not specified)
Description:
The issue is related to insufficient input validation of SNMP packets, which could allow an authenticated, remote attacker to cause an unexpected reload of the device, resulting in a denial of service (DoS) condition. This affects all versions of SNMP (versions 1, 2c, and 3) and requires a valid SNMP community string or valid SNMPv3 user credentials. An attacker could exploit this by sending a crafted SNMP request to an affected device using IPv4 or IPv6.
Recommendations:
For Cisco Adaptive Security Appliance (ASA) Software, consider disabling the SNMP feature until a patch is available.
For Cisco Firepower Threat Defense (FTD) Software, restrict access to the SNMP protocol to minimize the risk of exploitation.
As a temporary workaround, avoid using the
SNMP community string or SNMPv3 user credentials in the affected API endpoints until the issue is resolved.
At the moment, there is no information about a newer version that contains a fix for this vulnerability.DoS
