Multiple vulnerabilities in Red Hat OpenShift Container Platform

1) Inclusion of Sensitive Information in Log Files

EUVDB-ID: #VU48977

Risk: Low

CVSSv4.0: 4.3 [CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N/E:U/U:Clear]

CVE-ID: CVE-2020-8564

CWE-ID: CWE-532 - Information Exposure Through Log Files

Exploit availability: No

Description

The vulnerability allows a local user to gain access to sensitive information.

The vulnerability exists due to software stores sensitive information into log files. In Kubernetes clusters using a logging level of at least 4, processing a malformed docker config file will result in the contents of the docker config file being leaked, which can include pull secrets or other registry credentials. A local user can read the log files and gain access to sensitive data.

Mitigation

Install updates from vendor's website.

2) Buffer overflow

EUVDB-ID: #VU48780

Risk: High

CVSSv4.0: 8.1 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Amber]

CVE-ID: CVE-2015-8011

CWE-ID: CWE-119 - Memory corruption

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 within the lldp_decode() function in daemon/protocols/lldp.c in lldpd. A remote attacker can pass specially crafted data to the application, trigger memory corruption and execute arbitrary code on the target system.

Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.

Mitigation

Install updates from vendor's website.

3) Infinite loop

EUVDB-ID: #VU32881

Risk: Medium

CVSSv4.0: 6.6 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Green]

CVE-ID: CVE-2019-20907

CWE-ID: CWE-835 - Loop with Unreachable Exit Condition ('Infinite Loop')

Exploit availability: No

Description

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

The vulnerability exists due to infinite loop In Lib/tarfile.py in Python. A remote attacker can create a specially crafted TAR archive leading to an infinite loop when opened by tarfile.open, because _proc_pax lacks header validation.

Mitigation

Install updates from vendor's website.

4) Improper Neutralization of HTTP Headers for Scripting Syntax

EUVDB-ID: #VU29290

Risk: Low

CVSSv4.0: 1 [CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:A/VC:N/VI:L/VA:N/SC:N/SI:N/SA:N/E:U/U:Clear]

CVE-ID: CVE-2020-8177

CWE-ID: CWE-644 - Improper Neutralization of HTTP Headers for Scripting Syntax

Exploit availability: No

Description

The vulnerability allows a remote attacker to overwrite files on the victim's system.

The vulnerability exists due to a logical error when processing Content-Disposition: HTTP response header in curl when executed with the -J flag and -i flags in the same command line. A remote attacker can trick the victim to run a specially crafted curl command against a malicious website and overwrite files on the user's system.

Mitigation

Install updates from vendor's website.
