Aliases: CVE-2019-10081 |
HTTP/2 (2.4.20 through 2.4.39) very early pushes, for example configured with "H2PushResource", could lead to an overwrite of memory in the pushing request's pool, leading to crashes. The memory copied is that of the configured push link header values, not data supplied by the client. |

VCID-cwce-397z-aaak
Aliases: CVE-2020-11993 |
Apache HTTP Server versions 2.4.20 to 2.4.43 When trace/debug was enabled for the HTTP/2 module and on certain traffic edge patterns, logging statements were made on the wrong connection, causing concurrent use of memory pools. Configuring the LogLevel of mod_http2 above "info" will mitigate this vulnerability for unpatched servers. |
Affected by 10 other vulnerabilities. |
|
VCID-cwwm-tz2r-aaan
Aliases: CVE-2019-0220 |
A vulnerability was found in Apache HTTP Server 2.4.0 to 2.4.38. When the path component of a request URL contains multiple consecutive slashes ('/'), directives such as LocationMatch and RewriteRule must account for duplicates in regular expressions while other aspects of the servers processing will implicitly collapse them. |
Affected by 17 other vulnerabilities. |
|
VCID-dt6a-dc5k-aaak
Aliases: CVE-2020-11984 |
Apache HTTP server 2.4.32 to 2.4.44 mod_proxy_uwsgi info disclosure and possible RCE |
Affected by 10 other vulnerabilities. |
|
VCID-ebqh-gauj-aaac
Aliases: CVE-2020-11985 |
IP address spoofing when proxying using mod_remoteip and mod_rewrite For configurations using proxying with mod_remoteip and certain mod_rewrite rules, an attacker could spoof their IP address for logging and PHP scripts. Note this issue was fixed in Apache HTTP Server 2.4.24 but was retrospectively allocated a low severity CVE in 2020. |
Affected by 18 other vulnerabilities. |
|
VCID-fccq-2kpj-aaap
Aliases: CVE-2021-36160 |
A carefully crafted request uri-path can cause mod_proxy_uwsgi to read above the allocated memory and crash (DoS). This issue affects Apache HTTP Server versions 2.4.30 to 2.4.48 (inclusive). |
Affected by 1 other vulnerability. |
|
VCID-gtfr-3t82-aaab
Aliases: CVE-2019-9517 |
Some HTTP/2 implementations are vulnerable to unconstrained interal data buffering, potentially leading to a denial of service. The attacker opens the HTTP/2 window so the peer can send without constraint; however, they leave the TCP window closed so the peer cannot actually write (many of) the bytes on the wire. The attacker then sends a stream of requests for a large response object. Depending on how the servers queue the responses, this can consume excess memory, CPU, or both. |
Affected by 19 other vulnerabilities. |

VCID-kcnv-z2rj-aaaa
Aliases: CVE-2021-39275 |
ap_escape_quotes() may write beyond the end of a buffer when given malicious input. No included modules pass untrusted data to these functions, but third-party / external modules may. This issue affects Apache HTTP Server 2.4.48 and earlier. |
Affected by 1 other vulnerability. |

VCID-ncxa-2sp4-aaam
Aliases: CVE-2019-10092 |
In Apache HTTP Server 2.4.0-2.4.39, 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 malformed 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. |
Affected by 15 other vulnerabilities. |

VCID-qz6b-x9ps-aaae
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 |
Affected by 5 other vulnerabilities. |

VCID-rdww-rdku-aaas
Aliases: CVE-2020-1927 |
In Apache HTTP Server 2.4.0 to 2.4.41, redirects configured with mod_rewrite 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. |
Affected by 10 other vulnerabilities. |

VCID-tnr1-zca1-aaaq
Aliases: CVE-2021-34798 |
Malformed requests may cause the server to dereference a NULL pointer. This issue affects Apache HTTP Server 2.4.48 and earlier. |
Affected by 1 other vulnerability. |
|
VCID-vtj3-6vp1-aaap
Aliases: CVE-2019-0197 |
A vulnerability was found in Apache HTTP Server 2.4.34 to 2.4.38. When HTTP/2 was enabled for a http: host or H2Upgrade was enabled for h2 on a https: host, an Upgrade request from http/1.1 to http/2 that was not the first request on a connection could lead to a misconfiguration and crash. Server that never enabled the h2 protocol or that only enabled it for https: and did not set "H2Upgrade on" are unaffected by this issue. |
Affected by 19 other vulnerabilities. |
|
VCID-ytrc-wygq-aaaf
Aliases: CVE-2020-9490 |
Apache HTTP Server versions 2.4.20 to 2.4.43. A specially crafted value for the 'Cache-Digest' header in a HTTP/2 request would result in a crash when the server actually tries to HTTP/2 PUSH a resource afterwards. Configuring the HTTP/2 feature via "H2Push off" will mitigate this vulnerability for unpatched servers. |
Affected by 10 other vulnerabilities. |
|
VCID-z9au-scjh-aaae
Aliases: CVE-2021-33193 |
A crafted method sent through HTTP/2 will bypass validation and be forwarded by mod_proxy, which can lead to request splitting or cache poisoning. This issue affects Apache HTTP Server 2.4.17 to 2.4.48. |
