Description

This security bulletin contains information about 5 secuirty vulnerabilities.


1) Stack-based buffer overflow (CVE-ID: CVE-2022-28331)

The vulnerability allows a remote attacker to execute arbitrary code on the target system.

The vulnerability exists due to a boundary error within the apr_socket_sendv() function. A remote attacker can pass specially crafted input to the application, trigger a stack-based buffer overflow and execute arbitrary code on the target system.

Note, the vulnerability affects Windows installations only.


2) Inconsistent interpretation of HTTP requests (CVE-ID: CVE-2022-36760)

The vulnerability allows a remote attacker to perform HTTP request smuggling attacks.

The vulnerability exists due to improper validation of HTTP requests in mod_proxy_ajp. A remote attacker can send a specially crafted HTTP request to the web server and smuggle arbitrary HTTP headers to the AJP server it forwards requests to.

Successful exploitation of vulnerability may allow an attacker to poison HTTP cache and perform phishing attacks.


3) HTTP response splitting (CVE-ID: CVE-2022-37436)

The vulnerability allows a remote attacker to perform HTTP splitting attacks.

The vulnerability exists due to software does not correctly process CRLF character sequences within the mod_proxy module. A remote attacker can send specially crafted request containing CRLF sequence and make the application to send a split HTTP response.

Successful exploitation of the vulnerability may allow an attacker perform cache poisoning attack.


4) Buffer overflow (CVE-ID: CVE-2006-20001)

The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to a boundary error within the mod_dav module when handling HTTP requests. A remote attacker can send a specially crafted HTTP request, trigger a one byte buffer overflow and perform a denial of service (DoS) attack.


5) Integer overflow (CVE-ID: CVE-2022-25147)

The vulnerability allows a remote attacker to execute arbitrary code on the target system.

The vulnerability exists due to integer overflow within the apr_base64() function. A remote attacker can pass specially crafted data to the application, trigger an integer overflow and execute arbitrary code on the target system.

Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
