03 Exploitation and scoring

Exploitation

Public exploit code exists. CISA's assessment records a public proof of concept. That is not a report of exploitation in the wild.

SSVC decision

ExploitationpocPublic proof-of-concept exploit code exists. Not a report of exploitation in the wild.
AutomatablenoAt least one step from reconnaissance to exploitation cannot be reliably automated.
Technical ImpactpartialSuccessful exploitation gives limited control of the vulnerable component.

CISA publishes the decision points, not a final SSVC decision. The decision also depends on mission and well-being impact, which is a property of your deployment rather than of the vulnerability.

EPSS probability

0.34% probability of exploitation activity in the next 30 days.

EPSS percentile

Ranks above 26.8% of scored records. A rank, not a probability.

NVD base score

6.5 (CVSS v3.x), scored by the NVD independently of the CNA.

07 Remediation

The recommended resolution is to upgrade to a remediated software version at your earliest convenience. Arista recommends customers move to the latest version of each release that contains all the fixes listed below. For more information about upgrading see the MOS User Guide: Updating https://mako.arista.com/dyn/softwareportal/artefact/3688/mos-0.39.1-userguide.pdf CVE-2023-24547 has been fixed in the following releases: * MOS-0.36.10 and later releases in the MOS-0.36.x train * MOS-0.39.4 and later releases in the MOS-0.39.x train Because this issue would cause the password to be saved in logs and remote AAA servers it is recommended to also rotate the BGP password, if possible. Upon upgrading to a new release, the BGP password will be obfuscated with the type-7 algorithm as shown below: switch>show running-config bgp router bgp 65000 neighbor 192.0.2.1 remote-as 66000 neighbor 192.0.2.1 password key 7 00143242404C5B140B

HotfixThe following hotfix can be applied to remediate CVE-2023-24547. The hotfix only applies to the releases listed below and no other releases. All other versions require upgrading to a release containing the fix (as listed above): * MOS-0.39.3 and below releases in the MOS-0.39.x train * MOS-0.38.1 and below releases in the MOS-0.38.x train * MOS-0.37.1 and below releases in the MOS-0.37.x train * MOS-0.36.9 and below releases in the MOS-0.36.x train * MOS-0.35.3 and below releases in the MOS-0.35.x train * MOS-0.34.0 in the MOS-0.34.x train Please note that the only MOS release trains currently under maintenance support are MOS-0.39.x and MOS-0.36.x. The hotfix working for other releases should not be treated as evidence that these releases continue to be supported. For security it is important to ensure supported releases are used.
