Security Bulletin

This security bulletin contains information about 5 vulnerabilities.

1) Security restrictions bypass

EUVDB-ID: #VU60972

Risk: Medium

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

CVE-ID: CVE-2022-23648

CWE-ID: CWE-264 - Permissions, Privileges, and Access Controls

Exploit availability: Yes

Description

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

The vulnerability exists due to an error when handling specially crafted image configuration in containerd where containers launched through containerd’s CRI implementation. A remote attacker can bypass any policy-based enforcement on container setup and access the read-only copies of arbitrary files and directories on the host.

Mitigation

Install update from vendor's website.

Vulnerable software versions

IBM supplied MQ Advanced container images: before 9.3.1.0

IBM MQ Operator LTS: before 2.0.4

IBM MQ Operator CD: before 2.1.0

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. However, proof of concept for this vulnerability is available.

2) Improper Verification of Cryptographic Signature

EUVDB-ID: #VU64909

Risk: Medium

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

CVE-ID: CVE-2022-34903

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

Exploit availability: No

Description

The vulnerability allows a remote attacker to perform spoofing attack.

The vulnerability exists due to an error in GnuPG, which allows signature spoofing via arbitrary injection into the status line. A remote attacker who controls the secret part of any signing-capable key or subkey in the victim's keyring, can take advantage of this flaw to provide a correctly-formed signature that some software, including gpgme, will accept to have validity and signer fingerprint chosen from the attacker.

Mitigation

Install update from vendor's website.

3) Permissions, Privileges, and Access Controls

EUVDB-ID: #VU22482

Risk: Low

CVSSv3.1: 5.3 [CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:L/I:H/A:N/E:U/RL:O/RC:C]

CVE-ID: CVE-2019-16884

CWE-ID: CWE-264 - Permissions, Privileges, and Access Controls

Exploit availability: No

Description

The vulnerability allows a local user to escalate privileges on the system.

The vulnerability exists due to incorrect checking of the mount targets in libcontainer/rootfs_linux.go in runc. A local user can bypass AppArmor restrictions and perform unauthorized actions on the system, as demonstrated by overwriting the /proc directory with a malicious Doker image.

Mitigation

Install update from vendor's website.

http://www.ibm.com/support/pages/node/6830587


Q & A

Can this vulnerability be exploited remotely?

No. This vulnerability can be exploited locally. The attacker should have authentication credentials and successfully authenticate on the system.

Is there known malware, which exploits this vulnerability?

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

4) Authentication Bypass by Spoofing

EUVDB-ID: #VU65845

Risk: Medium

CVSSv3.1: 7.7 [CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H/E:U/RL:O/RC:C]

CVE-ID: CVE-2022-22476

CWE-ID: CWE-290 - Authentication Bypass by Spoofing

Exploit availability: No

Description

The vulnerability allows a remote attacker to execute identity spoofing attacks.

The vulnerability exists due to an unspecified error in IBM WebSphere Application Server Liberty. A remote authenticated user can send a specially crafted request to perform identity spoofing attacks.

Mitigation

Install update from vendor's website.

CVE-ID: CVE-2021-30465

CWE-ID: CWE-254 - Security Features

Exploit availability: No

Description

The vulnerability allows a remote attacker to compromise the target system.

The vulnerability exists due to the security features bypass issue. A remote authenticated attacker on the local network can perform a symlink exchange attack and host filesystem being bind-mounted into the container.

Mitigation

Install update from vendor's website.
