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

Details

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.

Severity

4.9 (Medium)

Detection rules are retrieved from Rulezet.

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base model, served locally by ML-Gateway. They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
