Cisco Bug: CSCur19653 - WSA certs being signed SHA1 with SHA256 CA - RSA
Mar 01, 2019
- Cisco Web Security Appliance
Known Affected Releases
7.7.0-757 8.5.0-000 8.5.0-beta1-333 8.5.2-000
Symptom: When uploading a SHA256 RSA root/intermediate certificate onto the WSA for HTTPS decryption, the WSA resigns the server certificate as SHA1 and sends it to the client. Conditions: Under Security Services>HTTPS Proxy the uploaded RSA certificate is a SHA256 root/intermediate certificate. You cannot generate a SHA256 CSR from the WSA; it must be created from an internal certificate authority such as Active Directory Certificate Service or with the OpenSSL client in Linux. The decryption policy for the Origin Content Server (OCS) must be set to "decrypt".
