Signature verification vulnerability in Stark Bank ecdsa libraries
GHSA-9wx7-jrvc-28mm
- Affected
- Maven com.starkbank:ecdsa-java >= 1.0.0, <= 1.0.0
- Fixed in
- 1.0.1· Vendor fix available
- Issue
- An attacker can forge signatures on arbitrary messages that will verify for any public key. This may allow attackers to authenticate as any user within the Stark Bank platform, and bypass signature verification needed to perform operations on the platform, such as send payments and transfer funds. Additionally, the ability for attackers to forge signatures may impact other users and projects using these libraries in different and unforeseen ways.
Recommended action: Upgrade to 1.0.1 or later, then redeploy and verify.A vendor fix does not resolve your finding until you verify it in your own systems.
