Security Bulletin

This security bulletin contains information about 17 vulnerabilities.

1) Improper Authentication

EUVDB-ID: #VU64089

Risk: Medium

CVSSv3.1: 5.7 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:N/E:U/RL:O/RC:C]

CVE-ID: CVE-2022-31813

CWE-ID: CWE-287 - Improper Authentication

Exploit availability: No

Description

The vulnerability allows a remote attacker to bypass authentication process.

The vulnerability exists due to an error in mod_proxy implementation, where the web server may not send the X-Forwarded-* headers to the origin server based on client side Connection header hop-by-hop mechanism. A remote attacker can bypass IP based authentication on the origin server/application and gain access to otherwise restricted functionality.

Mitigation

Install updates from vendor's website.

CVE-ID: CVE-2022-42916

CWE-ID: CWE-319 - Cleartext Transmission of Sensitive Information

Exploit availability: No

Description

CVSSv3.1: 6.5 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H/E:U/RL:O/RC:C]

CVE-ID: CVE-2022-42915

CWE-ID: CWE-415 - Double Free

Exploit availability: No

Description

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

The vulnerability exists due to a boundary error when processing non-200 proxy HTTP responses for the following schemes: dict, gopher, gophers, ldap, ldaps, rtmp, rtmps, telnet. A remote attacker can trigger a double free error by forcing the application into connecting to resources that are not allowed by the configured proxy.

4) Input validation error

EUVDB-ID: #VU66881

Risk: Medium

CVSSv3.1: 5.7 [CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:H/E:U/RL:O/RC:C]

CVE-ID: CVE-2022-35252

CWE-ID: CWE-20 - Improper input validation

Exploit availability: No

Description

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

The vulnerability exists due to the way curl handles cookies with control codes (byte values below 32). When cookies that contain such control codes are later sent back to an HTTP(S) server, it might make the server return a 400 response, effectively allowing a "sister site" to deny service to siblings.

Mitigation

Install updates from vendor's website.

5) Expected behavior violation

EUVDB-ID: #VU68746

Risk: Medium

CVSSv3.1: 4.7 [CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:L/I:L/A:N/E:U/RL:O/RC:C]

CVE-ID: CVE-2022-32221

CWE-ID: CWE-440 - Expected Behavior Violation

Exploit availability: No

Description

The vulnerability allows a remote attacker to force unexpected application behavior.

The vulnerability exists due to a logic error for a reused handle when processing subsequent HTTP PUT and POST requests. The libcurl can erroneously use the read callback (CURLOPT_READFUNCTION) to ask for data to send, even when the CURLOPT_POSTFIELDS option has been set, if the same handle previously was used to issue a PUT request, which used that callback. As a result, such behavior can influence application flow and force unpredictable outcome.

Mitigation

Install updates from vendor's website.

CVE-ID: CVE-2022-32208

CWE-ID: CWE-347 - Improper Verification of Cryptographic Signature

CVE-ID: CVE-2022-32206

CWE-ID: CWE-400 - Resource exhaustion

Exploit availability: No

Description

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

The vulnerability exists due to insecure processing of compressed HTTP responses.

11) Out-of-bounds read

EUVDB-ID: #VU64083

Risk: Low

CVSSv3.1: 3.5 [CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:C/C:L/I:N/A:N/E:U/RL:O/RC:C]

CVE-ID: CVE-2022-28615

CWE-ID: CWE-125 - Out-of-bounds read

Exploit availability: No

Description

The vulnerability allows a remote attacker to gain access to potentially sensitive information.

The vulnerability exists due to a boundary condition within the ap_strcmp_match() function when processing an extremely large input buffer. A remote attacker can send a specially crafted HTTP request to the web server, trigger an out-of-bounds read error and read contents of memory on the system.

Note, the code distributed with the Apache HTTP Server cannot be coerced into such a call. The vulnerability can affect third-party modules or lua scripts that use ap_strcmp_match().

12) Out-of-bounds read

EUVDB-ID: #VU64081

Risk: Low

CVSSv3.1: 3.5 [CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:C/C:L/I:N/A:N/E:U/RL:O/RC:C]

CVE-ID: CVE-2022-28614

CWE-ID: CWE-125 - Out-of-bounds read

Exploit availability: No

Description

The vulnerability allows a remote attacker to gain access to potentially sensitive information.

The vulnerability exists due to a boundary condition within the ap_rwrite() function. A remote attacker can with the ability to force the server to reflect a very large input using ap_rwrite() or ap_rputs() (such as with mod_luas r:puts() function) can trigger an out-of-bounds read error and read read unintended memory on the system.

Mitigation

Install updates from vendor's website.
