CVE-ID: CVE-2021-44224

CWE-ID: CWE-918 - Server-Side Request Forgery (SSRF)

Exploit availability: No

Description

The disclosed vulnerability allows a remote attacker to perform SSRF attacks.

The vulnerability exists due to insufficient validation of user-supplied input in forward proxy configurations. A remote attacker can send a specially crafted HTTP request and trick the web server to initiate requests to arbitrary systems or cause NULL pointer dereference error and crash the web server.

Successful exploitation of this vulnerability may allow a remote attacker gain access to sensitive data, located in the local network or send malicious requests to other servers from the vulnerable system.

SSRF if possible for configuration that mix forward and reverse proxy.

19) Buffer overflow

EUVDB-ID: #VU56679

Risk: Medium

CVSSv3.1: 4.9 [CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:L/I:L/A:L/E:U/RL:O/RC:C]

CVE-ID: CVE-2021-39275

CWE-ID: CWE-119 - Memory corruption

Exploit availability: No

Description

The vulnerability allows a remote attacker to execute arbitrary code on the target system or perform a denial of service attack.

The vulnerability exists due to a boundary error within the ap_escape_quotes() function. A remote attacker can send a specially crafted request to the web server, trigger memory corruption and execute arbitrary code on the target system.

Successful exploitation of this vulnerability may result in complete compromise of vulnerable system but requires that the Apache module passes untrusted data to the affected function.

According to vendor, No included modules pass untrusted data to these functions

Mitigation

Install updates from vendor's website.
