Here's a brief report:
: While not a vulnerability in Apache core, misconfigurations or specific rules in mod_security could lead to issues.
There are public exploits available for this vulnerability. One example is: apache 2.4 6 exploit
The most notable "story" involving version 2.4.6 surfaced years after its prime. In 2021, researchers identified a critical flaw (CVE-2019-17567) involving mod_proxy_wstunnel .
Disable mod_status if it is not required, or strictly limit access to trusted IP addresses. 2. mod_cache Null Pointer Dereference (CVE-2013-4352) Here's a brief report: : While not a
The story gets complicated because Apache 2.4.6 is often confused with its much more famous (and dangerous) younger sibling, . In late 2021, a "Path Traversal" bug (CVE-2021-41773) set the internet on fire.
This can lead to a heap-based buffer overflow, potentially allowing the attacker to crash the child process or execute code with the privileges of the web server user. The server process crashes
The server process crashes, preventing legitimate users from accessing hosted websites. While this doesn't typically lead to data theft, it is highly effective at disrupting services. 3. HTTP Request/Response Smuggling (Various CVEs)
The story of the exploit is a classic tale of a "silent sleeper"—a vulnerability that sat quietly in data centers for years before being rediscovered.
Attackers exploit inconsistencies in how the Apache proxy (like mod_proxy_wstunnel ) and the backend server interpret malformed HTTP requests.
