Title

Cisco SD-WAN vDaemon Buffer Overflow Vulnerability

Summary

A vulnerability in the vDaemon service of Cisco SD-WAN vManage Software could allow an authenticated, local attacker to cause a buffer overflow on an affected system, resulting in a denial of service (DoS) condition. The vulnerability is due to incomplete bounds checks for data that is provided to the vDaemon service of an affected system. An attacker could exploit this vulnerability by sending malicious data to the vDaemon listening service on the affected system. A successful exploit could allow the attacker to cause a buffer overflow condition on the affected system, which could allow the attacker to cause the vDaemon listening service to reload and result in a DoS condition.Cisco has released software updates that address this vulnerability. There are no workarounds that address this vulnerability.

Summary

Cisco SD-WAN vDaemon Buffer Overflow Vulnerability

Notes

Summary

A vulnerability in the vDaemon service of Cisco SD-WAN vManage Software could allow an authenticated, local attacker to cause a buffer overflow on an affected system, resulting in a denial of service (DoS) condition. The vulnerability is due to incomplete bounds checks for data that is provided to the vDaemon service of an affected system. An attacker could exploit this vulnerability by sending malicious data to the vDaemon listening service on the affected system. A successful exploit could allow the attacker to cause a buffer overflow condition on the affected system, which could allow the attacker to cause the vDaemon listening service to reload and result in a DoS condition. Cisco has released software updates that address this vulnerability. There are no workarounds that address this vulnerability.

Vulnerable Products

At the time of publication, this vulnerability affected Cisco SD-WAN vManage Software releases earlier than the following releases: 18.4.5 19.2.3 20.1.12 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 Cisco SD-WAN vManage Software releases contained the fix for this vulnerability: 18.4.5 and later 19.2.3 and later 20.1.12 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.

GHSA-V999-55FC-W9WW

Vulnerability from github – Published: 2024-11-15 18:30 – Updated: 2024-11-15 18:30

Details

A vulnerability in the vDaemon service of Cisco SD-WAN vManage Software could allow an authenticated, local attacker to cause a buffer overflow on an affected system, resulting in a denial of service (DoS) condition. The vulnerability is due to incomplete bounds checks for data that is provided to the vDaemon service of an affected system. An attacker could exploit this vulnerability by sending malicious data to the vDaemon listening service on the affected system. A successful exploit could allow the attacker to cause a buffer overflow condition on the affected system, which could allow the attacker to cause the vDaemon listening service to reload and result in a DoS condition.Cisco has released software updates that address this vulnerability. There are no workarounds that address this vulnerability.

Severity ?

5.4 (Medium)
