Vulnerability from csaf_cisco - Published: 2021-03-03 16:00 - Updated: 2021-03-03 16:00

Summary

Cisco SD-WAN Software Signature Verification Bypass Vulnerability

Notes

Summary

A vulnerability in the Image Signature Verification feature of Cisco SD-WAN Software could allow an authenticated, remote attacker with Administrator-level credentials to install a malicious software patch on an affected device. The vulnerability is due to improper verification of digital signatures for patch images. An attacker could exploit this vulnerability by crafting an unsigned software patch to bypass signature checks and loading it on an affected device. A successful exploit could allow the attacker to boot a malicious software patch image. Cisco has released software updates that address the vulnerability described in this advisory. There are no workarounds that address this vulnerability.

Vulnerable Products

At the time of publication, this vulnerability affected Cisco SD-WAN vEdge Router software and Cisco SD-WAN vManage Software releases earlier than the following releases: 18.4.5 19.2.2 20.1.1 20.3.1 20.4.1 See the Details section in the bug ID(s) at the top of this advisory for the most complete and current information.

Products Confirmed Not Vulnerable

Only products listed in the Vulnerable Products ["#vp"] section of this advisory are known to be affected by this vulnerability.

Workarounds

There are no workarounds that address this vulnerability.

Fixed Software

When considering software upgrades ["https://sec.cloudapps.cisco.com/security/center/resources/security_vulnerability_policy.html#fixes"], customers are advised to regularly consult the advisories for Cisco products, which are available from the Cisco Security Advisories page ["https://www.cisco.com/go/psirt"], to determine exposure and a complete upgrade solution. In all cases, customers should ensure that the devices to be upgraded contain sufficient memory and confirm that current hardware and software configurations will continue to be supported properly by the new release. If the information is not clear, customers are advised to contact the Cisco Technical Assistance Center (TAC) or their contracted maintenance providers. Fixed Releases At the time of publication, the following releases of Cisco SD-WAN vEdge Router software and Cisco SD-WAN vManage Software contained the fix for this vulnerability: 18.4.5 and later 19.2.2 and later 20.1.1 and later 20.3.1 and later 20.4.1 and later See the Details section in the bug ID(s) at the top of this advisory for the most complete and current information.
