AI Analysis
Technical Summary
The go-ntlmssp package used in Azure for NTLM/Negotiate HTTP authentication versions prior to 0.1.1 contains an integer overflow vulnerability (CWE-190). A specially crafted malicious NTLM challenge message can trigger a slice out of bounds panic, causing the Go process using ntlmssp.Negotiator as HTTP transport to crash. This denial of service condition is addressed by a patch released in version 0.1.1. The vulnerability has a CVSS 3.1 base score of 5.3 (medium severity) with network attack vector, low attack complexity, no privileges or user interaction required, and impacts availability only. The vendor manages remediation for this cloud-hosted service, and users should upgrade to version 0.1.1 or later.
Potential Impact
Exploitation of this vulnerability results in a denial of service by crashing the Go process handling NTLM authentication due to a slice out of bounds panic triggered by a malicious NTLM challenge message. There is no impact on confidentiality or integrity. No known exploits are reported in the wild.
Mitigation Recommendations
A patch is available in go-ntlmssp version 0.1.1 that fixes this vulnerability. Users and administrators should upgrade to version 0.1.1 or later to remediate the issue. Since this is a cloud service managed by the vendor, the vendor typically handles patching for hosted environments. Check the vendor advisory for confirmation of remediation status in cloud deployments.
