- Summary
- Coder: PKCS#7 signature bypass in Azure instance identity allows unauthenticated agent token theft
- Details
-
Coder allows organizations to provision remote development environments via Terraform. In versions prior tp 2.24.5, 2.29.13, 2.30.8, 2.31.12, 2.32.2, and 2.33.3,
azureidentity.Validate()verifies that the PKCS#7 signer certificate chains to a trusted Azure CA but never verifies the PKCS#7 signature itself. An attacker can embed a legitimate Azure certificate alongside arbitrary content e.g.{"vmId":"<target>"}and the forgedvmIdwill be accepted returning the victim workspace agent's session token. No authentication is required. The attacker only needs to know a target VM'svmIdwhich is aUUIDv4. That's a practical limitation which would typically require prior access to be exploited. Versions 2.24.5, 2.29.13, 2.30.8, 2.31.12, 2.32.2, and 2.33.3 patch the issue. As a workaround, reconfigure any Azure templates to use token authentication rather thanazure-instance-identity. - Database specific
