Article Number

000068085

Applies To

Identity Router v2.17 update. ( Jan Release)

Issue

The IDR web resource are not accessible and are failing with following error in /var/log/symplified/*-error.log file.
[ssl:info] AH02008: SSL library error 1 in handshake
[ssl:info] SSL Library Error: error:1408A0C1:SSL routines:ssl3_get_client_hello:no shared cipher – Too restrictive SSLCipherSuite or using DSA server certificate?
[ssl:info] AH01998: Connection closed to child 20 with abortive shutdown

Cause

In IDR v2.17: TLS_RSA_WITH_AES_256_CBC_SHA256 (0x003d) [openssl name - AES256-SHA256] and TLS_RSA_WITH_AES_256_CBC_SHA (0x0035) [openssl name- AES256-SHA] are broken and fix is being pushed as part of Cloud Feb release.

If client apps in customer environment (browser/REST clients) are having only these two common ciphers in their cipher suites, the IDR web resource will be inaccessible due to no shared cipher.

Resolution

These 2 ciphers will be fixed as part of Cloud Feb release 2023

Workaround

Include more common cipher in the client side cipher suites. To find the other ciphers IDR support, please check https://community.rsa.com/t5/securid-cloud-authentication/security-levels-and-identity-router-connection-ciphers/ta-p/622927
