CVE-ID: CVE-2021-44832

CWE-ID: CWE-94 - Improper Control of Generation of Code ('Code Injection')

Exploit availability: No

Description

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

The vulnerability exists due to improper input validation. A remote user with permission to modify the logging configuration file can construct a malicious configuration using a JDBC Appender with a data source referencing a JNDI URI which can execute remote code.

Mitigation

Install updates from vendor's website.

Vulnerable software versions

Red Hat OpenShift Container Platform: 4.6.0 - 4.6.53

2) Input validation error

EUVDB-ID: #VU22598

Risk: Low

CVSSv3.1: 2.5 [CVSS:3.1/AV:L/AC:L/PR:L/UI:R/S:U/C:L/I:N/A:N/E:U/RL:O/RC:C]

CVE-ID: CVE-2019-14866

CWE-ID: CWE-20 - Improper Input Validation

Exploit availability: No

Description

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

The vulnerability exists due to GNU cpio does not properly validate files when writing tar headers during tar archive creation. A local user can trick the victim into creating a tar archive out of a directory with specially crafted files. As a result the generated archive may contain files that the attacker does not have access to.

Mitigation

Install updates from vendor's website.

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.

3) Improper Resource Shutdown or Release

EUVDB-ID: #VU59473

Risk: Low

CVSSv3.1: 4.8 [CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H/E:U/RL:O/RC:C]

CVE-ID: CVE-2020-36322

CWE-ID: CWE-404 - Improper Resource Shutdown or Release

Exploit availability: No

Description

The vulnerability allows a local user to perform a denial of service (DoS) attack.

The vulnerability exists in the FUSE filesystem implementation in the Linux kernel due to fuse_do_getattr() calls make_bad_inode() in inappropriate situations. A local user can run a specially crafted program to trigger kernel crash.

Note, the vulnerability exists due to incomplete fix for #VU58207 (CVE-2021-28950).

Mitigation

Install updates from vendor's website.
