VCID-3djp-gq4c-1fa9
Aliases: CVE-2019-10092 |
A limited cross-site scripting issue was reported affecting the mod_proxy error page. An attacker could cause the link on the error page to be malfomed and instead point to a page of their choice. This would only be exploitable where a server was set up with proxying enabled but was misconfigured in such a way that the Proxy Error page was displayed. We have taken this opportunity to also remove request data from many other in-built error messages. Note however this issue did not affect them directly and their output was already escaped to prevent cross-site scripting attacks. |

VCID-3wuk-hwg1-6fa6
Aliases: CVE-2015-3185 |
A design error in the "ap_some_auth_required" function renders the API unusuable in httpd 2.4.x. In particular the API is documented to answering if the request required authentication but only answers if there are Require lines in the applicable configuration. Since 2.4.x Require lines are used for authorization as well and can appear in configurations even when no authentication is required and the request is entirely unrestricted. This could lead to modules using this API to allow access when they should otherwise not do so. API users should use the new ap_some_authn_required API added in 2.4.16 instead. |

VCID-66k7-maf9-dfcd
Aliases: CVE-2020-35452 |
Apache HTTP Server versions 2.4.0 to 2.4.46 A specially crafted Digest nonce can cause a stack overflow in mod_auth_digest. There is no report of this overflow being exploitable, nor the Apache HTTP Server team could create one, though some particular compiler and/or compilation option might make it possible, with limited consequences anyway due to the size (a single byte) and the value (zero byte) of the overflow |

VCID-ct26-19cq-8kd7
Aliases: CVE-2018-17199 |
In Apache HTTP Server 2.4 release 2.4.37 and prior, mod_session checks the session expiry time before decoding the session. This causes session expiry time to be ignored for mod_session_cookie sessions since the expiry time is loaded when the session is decoded. |
Affected by 22 other vulnerabilities. |
