Low: mod_session response handling heap overflowĪpache HTTP Server versions 2.4.0 to 2.4.46 A specially crafted SessionHeader sent by an origin server could cause a heap overflowĪcknowledgements: Discovered internally Christophe Jaillet Reported to security team Low: mod_session NULL pointer dereferenceĪpache HTTP Server versions 2.4.0 to 2.4.46 A specially crafted Cookie header handled by mod_session can cause a NULL pointer dereference and crash, leading to a possible Denial Of Service 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 overflowĪcknowledgements: This issue was discovered and reported by GHSL team member (Antonio Morales) Reported to security team Low: mod_auth_digest possible stack overflow by one nul byteĪpache HTTP Server versions 2.4.0 to 2.4.46 A specially crafted Digest nonce can cause a stack overflow in mod_auth_digest. Low: mod_proxy_http NULL pointer dereferenceĪpache HTTP Server versions 2.4.41 to 2.4.46 mod_proxy_http can be made to crash (NULL pointer dereference) with specially crafted requests using both Content-Length and Transfer-Encoding headers, leading to a Denial of ServiceĪcknowledgements: Reported by Marc Stern () Reported to security team Inconsistent Interpretation of HTTP Requests ('HTTP Request Smuggling') vulnerability in mod_proxy_ajp of Apache HTTP Server allows an attacker to smuggle requests to the AJP server it forwards requests to. Fixed in Apache HTTP Server 2.4.54 moderate: mod_proxy_ajp: Possible request smuggling Consult the Apache httpd 2.2 vulnerabilities list for more information. The initial GA release, Apache httpd 2.4.1, includes fixes for all vulnerabilities which have been resolved in Apache httpd 2.2.22 and all older releases. Please send comments or corrections for these vulnerabilities to the Security Team.

Please note that if a vulnerability is shown below as being fixed in a "-dev" release then this means that a fix has been applied to the development source tree and will be part of an upcoming full release. We also list the versions the flaw is known to affect, and where a flaw has not been verified list the version with a question mark. Each vulnerability is given a security impact rating by the Apache security team - please note that this rating may well vary from platform to platform. Please check specific vendor advisory for more information.This page lists all security vulnerabilities fixed in released versions of Apache HTTP Server 2.4. Impact: Attackers can exploit this issue to bypass certain security restrictions and perform unauthorized actions.
Users who only use SSL without basic authentication or those who use Kerberos are not affected. So, if Solr users have enabled BasicAuth authentication mechanism using the BasicAuthPlugin or if the user has implemented a custom Authentication plugin, which does not implement either “ HttpClientInterceptorPlugin” or “ HttpClientBuilderPlugin“, his/her servers are vulnerable to this attack. This can trick the nodes in cluster to believe that the malicious node is a member of the cluster.
It is possible to create a specially crafted node name that does not exist as part of the cluster and point it to a malicious node. Description: Apache Solr uses a PKI based mechanism to secure inter-node communication when security is enabled.
