libcurl is vulnerable to Authentication Bypass
37
Low Risk
This Affects:
libcurlTL;DR
LDAP SASL authentication accepts an unfinished handshake as a completed cryptographic check. A peer that can modify the connection can inject a short response and skip the rest of peer validation, so the client accepts the LDAP peer without a finished SASL exchange. The fix requires the handshake to finish before it reports success.
Who does this affect?
You are affected if you are using a version that falls within the vulnerable range and you use LDAP with SASL authentication.
Background info
libcurl is vulnerable to Authentication Bypass in versions 7.82.0 - 8.21.0.
How to fix this
Upgrade the libcurl and/or the curl.curl library to the patch version.
