https://notcve.org/view.php?id=CVE-2019-0217
03 Apr 2019 — In Apache HTTP Server 2.4 release 2.4.38 and prior, a race condition in mod_auth_digest when running in a threaded server could allow a user with valid credentials to authenticate using another username, bypassing configured access control restrictions. En Apache HTTP Server 2.4 versión 2.4.38 y anteriores, una condición de carrera en mod_auth_digest cuando se ejecuta en un servidor multihilo podría permitir a un usuario con credenciales válidas autenticarse usando otro nombre de usuario, evitando las restr... • https://github.com/savsch/PoC_CVE-2019-0217 • CWE-284: Improper Access Control CWE-362: Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition') •

03 Apr 2019 — 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.

CVE-2018-17199 – httpd: mod_session_cookie does not respect expiry time
https://notcve.org/view.php?id=CVE-2018-17199
23 Jan 2019 — 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. En Apache HTTP Server 2.4, en sus distribuciones 2.4.37 y anteriores, mod_session comprueba el tiempo de caducidad de la sesión antes de descodificarla. Esto provoca que se ignore el tiempo de caducidad de la sesión para sesiones mod_session_cookie,... • http://www.securityfocus.com/bid/106742 • CWE-384: Session Fixation CWE-613: Insufficient Session Expiration •

CVE-2016-4975 – mod_userdir CRLF injection
https://notcve.org/view.php?id=CVE-2016-4975
14 Aug 2018 — Possible CRLF injection allowing HTTP response splitting attacks for sites which use mod_userdir. This issue was mitigated by changes made in 2.4.25 and 2.2.32 which prohibit CR or LF injection into the "Location" or other outbound header key or value. Fixed in Apache HTTP Server 2.4.25 (Affected 2.4.1-2.4.23). Fixed in Apache HTTP Server 2.2.32 (Affected 2.2.0-2.2.31). Posible inyección CRLF que permite ataques de separación de respuesta HTTP para los sitios que emplean mod_userdir. • http://www.securityfocus.com/bid/105093 • CWE-93: Improper Neutralization of CRLF Sequences ('CRLF Injection') CWE-113: Improper Neutralization of CRLF Sequences in HTTP Headers ('HTTP Request/Response Splitting') •

CVE-2017-15710 – httpd: Out of bounds write in mod_authnz_ldap when using too small Accept-Language values
https://notcve.org/view.php?id=CVE-2017-15710
26 Mar 2018 — In Apache httpd 2.0.23 to 2.0.65, 2.2.0 to 2.2.34, and 2.4.0 to 2.4.29, mod_authnz_ldap, if configured with AuthLDAPCharsetConfig, uses the Accept-Language header value to lookup the right charset encoding when verifying the user's credentials. If the header value is not present in the charset conversion table, a fallback mechanism is used to truncate it to a two characters value to allow a quick retry (for example, 'en-US' is truncated to 'en'). A header value of less than two characters forces an out of b... • http://www.openwall.com/lists/oss-security/2018/03/24/8 • CWE-787: Out-of-bounds Write •

CVE-2018-1283 – httpd: Improper handling of headers in mod_session can allow a remote user to modify session data for CGI applications
https://notcve.org/view.php?id=CVE-2018-1283
26 Mar 2018 — In Apache httpd 2.4.0 to 2.4.29, when mod_session is configured to forward its session data to CGI applications (SessionEnv on, not the default), a remote user may influence their content by using a "Session" header. This comes from the "HTTP_SESSION" variable name used by mod_session to forward its data to CGIs, since the prefix "HTTP_" is also used by the Apache HTTP Server to pass HTTP header fields, per CGI specifications. En Apache httpd, versiones 2.4.0 hasta la 2.4.29, cuando se configura mod_session... • http://www.openwall.com/lists/oss-security/2018/03/24/4 • CWE-20: Improper Input Validation •

CVE-2018-1303 – httpd: Out of bounds read in mod_cache_socache can allow a remote attacker to cause DoS

26 Mar 2018 — A specially crafted HTTP request header could have crashed the Apache HTTP Server prior to version 2.4.30 due to an out of bound read while preparing data to be cached in shared memory. It could be used as a Denial of Service attack against users of mod_cache_socache. The vulnerability is considered as low risk since mod_cache_socache is not widely used, mod_cache_disk is not concerned by this vulnerability.

26 Mar 2018 — In Apache httpd 2.2.0 to 2.4.29, when generating an HTTP Digest authentication challenge, the nonce sent to prevent reply attacks was not correctly generated using a pseudo-random seed. In a cluster of servers using a common Digest authentication configuration, HTTP requests could be replayed across servers by an attacker without detection.

CVE-2018-1301 – httpd: Out of bounds access after failure in reading the HTTP request
https://notcve.org/view.php?id=CVE-2018-1301
26 Mar 2018 — A specially crafted request could have crashed the Apache HTTP Server prior to version 2.4.30, due to an out of bound access after a size limit is reached by reading the HTTP header. This vulnerability is considered very hard if not impossible to trigger in non-debug mode (both log and build level), so it is classified as low risk for common server usage.
