MEDIUMCVSS Vector
CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N
Lifecycle Timeline
2Description
IBM Common Cryptographic Architecture 7.0.0 through 7.5.51 could allow a remote attacker to obtain sensitive information during the creation of ECDSA signatures to perform a timing-based attack.
Analysis
IBM's Common Cryptographic Architecture (versions 7.0.0-7.5.51) contains a timing vulnerability in ECDSA signature generation that leaks sensitive information through how long the operation takes to complete. Attackers can exploit this timing difference to deduce the private signing key through repeated observations of signature creation times. Any organization using affected IBM CCA versions for cryptographic operations is at risk of having their ECDSA private keys compromised.
Technical Context
affects IBM Common Cryptographic Architecture 7.0.0. IBM Common Cryptographic Architecture 7.0.0 through 7.5.51
could allow a remote attacker to obtain sensitive information during the creation of ECDSA signatures to perform a timing-based attack.
Affected Products
Product: IBM Common Cryptographic Architecture 7.0.0. Versions: up to 7.5.51.
Remediation
Monitor vendor advisories for a patch. Restrict network access to the affected service where possible.
