Description William D. Hamblen 2023-11-13 17:18:51 UTC
Description of problem: The ~ (tilde) operator used to authorize based on a regex no longer works after the update from 1.1.3 to 1.2-4 at the end of March 2023.  


Version-Release number of selected component (if applicable): 1.2-4 


How reproducible: Easily.  A syntax like "require cas-attribute affil~^(?!ALUMNI).*$" will fail "no access" even when the attribute should be allowing access.


Steps to Reproduce:
1. Create an .htaccess file using the tilde syntax
2. Try to load the page
3. Will fail regardless of the attributes returned by the session validation call.

Actual results: Access denied.


Expected results: Access granted.


Additional info: Building from source tarball in the src.rpm without the "0002-Update-to-pcre2.patch" patch works fine so something in that seems almost certain to be the cause.

Comment 1 William D. Hamblen 2023-11-13 17:26:00 UTC
Note: EL8 is also affected by this.Probably all versions, but I've only checked 7 and 8.

Comment 2 Scott Williams 2023-11-13 18:50:57 UTC
Thanks for reporting this.  This regression might have been caused by a patch I had submitted upstream (https://github.com/apereo/mod_auth_cas/pull/209) and it looks like there was a proposed fix for this that dropped off my radar.  I'll get a build together shortly for you to test.

Comment 3 Scott Williams 2024-01-27 03:11:53 UTC
I pushed an update to the PR upstream that I think will fix this.  If they don't reply soon, I'll update the patch on our end so you can test it out.

Comment 4 William D. Hamblen 2024-01-27 14:01:19 UTC
Thanks, sounds good.  I'll keep an eye out for whichever.

Comment 5 Scott Williams 2024-02-20 22:58:38 UTC
I have good news!  The PRs were just approved and merged upstream.  We'll get an update for you to test shortly.

Comment 10 Scott Williams 2024-02-21 00:35:19 UTC
It should be fixed for EL8 and EL9 (and Fedora).  Unfortunately, EL7 no longer builds against the current mod_auth_cas as it's missing the apr_escape.h header that isn't currently available in EL7.
