CVE-2006-1116: The CBC-MAC integrity functions in the nCipher nCore API before 2.18 transmit the initialization vector IV...

The CBC-MAC integrity functions in the nCipher nCore API before 2.18 transmit the initialization vector IV as part of a message when the implementation uses a non-zero IV, which allows remote attackers to bypass integrity checks and modify messages without being detected.

Security readout for executives and security teams

This issue affects legacy use of nCipher's nCore API CBC-MAC integrity functions before version 2.18. In affected implementations, a message could be changed without the integrity check detecting it, undermining trust in protected data flows. Likely exposure is limited to legacy systems using nCipher nCore API versions before 2.18, specifically CBC-MAC integrity functions with non-zero IV usage. The source bundle does not identify affected CPEs or downstream products. Prioritize discovery if the organization has legacy nCipher deployments or custom cryptographic integrations. Business urgency depends on whether affected CBC-MAC paths protect important transactions, commands, or records. Without confirmed exposure, treat this as a targeted legacy-risk check rather than an enterprise-wide emergency. Mitigation focus: Inventory systems and applications using nCipher nCore API before 2.18.; Check the nCipher advisory for supported remediation guidance.; Move affected nCore API usage off versions before 2.18 where applicable..
