| Description |
| + |
A security issue has been found in Apache HTTP Server from 2.4.0 up to and including 2.4.41, in the mod_rewrite module, where redirects that were intended to be self-referential might be fooled by encoded newlines and redirect instead to an an unexpected URL within the request URL. |
| + |
This is the same defect as CVE-2019-10098. The fix for CVE-2019-10098 was ineffective. |
| + |
Possible mitigations are the use of anchor captures as back-references, or prefixing self-referential redirects with / or scheme, host, and port. |
