- →Upstream fix commits can be used to identify patched vs. unpatched binaries: 2.4 fix at commit 78f0f0b6585f13ec1175c7020ee01cd0237fc1ba, 2.2 fix at commit 7103baa2e70e37eeaf7847abaa6f3567ef2cdf73 ↗
- ·Vulnerability only manifests when third-party modules incorrectly use ap_get_basic_auth_pw() outside the authentication phase; vanilla Apache httpd without such modules is not directly exploitable via this code path ↗
- ·Affected versions are Apache httpd 2.2.x before 2.2.33 and 2.4.x before 2.4.26; detections should be scoped to these version ranges ↗
- ·The fix introduces a new ap_get_basic_auth_components() function for safe use by third-party modules; presence of this symbol in a loaded module indicates patched behavior ↗

CVE-2017-3167 [CRITICAL] CWE-287 httpd: ap_get_basic_auth_pw() authentication bypass
httpd: ap_get_basic_auth_pw() authentication bypass
In Apache httpd 2.2.x before 2.2.33 and 2.4.x before 2.4.26, use of the ap_get_basic_auth_pw() by third-party modules outside of the authentication phase may lead to authentication requirements being bypassed.
It was discovered that the use of httpd's ap_get_basic_auth_pw() API function outside of the authentication phase could lead to authentication bypass. A remote attacker could possibly use this flaw to bypass required authentication if the API was used incorrectly by one of the modules used by httpd.

Find a way in and learn a little more.
## Task 1
Well, the flaw that makes up this box is the reproduction found in the production environment of a customer a while ago, the verification in season consisted of two steps, the last one within the environment, we hit it head-on and more than 15 machines were vulnerable that together with the development team we were able to correct and adapt.
*First of all, add the jacobtheboss.box address to your hosts file.*
Anyway, learn a little more, have fun!
