Security Bulletin

This security bulletin contains information about 4 vulnerabilities.

1) Input validation error

EUVDB-ID: #VU64085

Risk: Medium

CVSSv3.1: 5.2 [CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:N/A:H/E:U/RL:O/RC:C]

CVE-ID: CVE-2022-29404

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 insufficient validation of user-supplied input when processing HTTP requests to a lua script that calls r:parsebody(0). A remote attacker can send a very large HTTP request to the affected web server and perform a denial of service (DoS) attack.

Mitigation

Install update from vendor's website.

Vulnerable software versions

App Connect Enterprise Certified Container: before 6.1.0

Q & A

Can this vulnerability be exploited remotely?

Yes. This vulnerability can be exploited by a remote non-authenticated attacker via the Internet.

Is there known malware, which exploits this vulnerability?

No. We are not aware of malware exploiting this vulnerability.

2) Resource exhaustion

EUVDB-ID: #VU64086

Risk: Medium

CVSSv3.1: 5.9 [CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:C/C:N/I:N/A:H/E:U/RL:O/RC:C]

CVE-ID: CVE-2022-30522

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 mod_sed does not properly control consumption of internal resources, if the web server is configured to do transformations with mod_sed in contexts where the input to mod_sed may be very large. A remote attacker can trigger resource exhaustion and perform a denial of service (DoS) attack.

Mitigation

Install update from vendor's website.

3) Out-of-bounds read

EUVDB-ID: #VU64088

Risk: Medium

CVSSv3.1: 5.9 [CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:C/C:H/I:N/A:N/E:U/RL:O/RC:C]

CVE-ID: CVE-2022-30556

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 when processing HTTP requests in mod_lua with websockets. A remote attacker can force the module to return lengths to applications calling r:wsread() that point past the end of the storage allocated for the buffer and gain access to sensitive information.

Mitigation

Install update from vendor's website.

4) 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 update from vendor's website.
