Security Bulletin
This security bulletin contains information about 2 vulnerabilities.
1) Code Injection
EUVDB-ID: #VU58976
Risk: High
CVSSv4.0: 9.2 [CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:A/U:Amber]
CVE-ID: CVE-2021-45046
CWE-ID:
CWE-94 - Improper Control of Generation of Code ('Code Injection')
Exploit availability: Yes
DescriptionThe vulnerability allows a remote attacker to compromise the affected system.
The
vulnerability exists due to incomplete patch in Apache Log4j 2.15.0 for
a code injection vulnerability #VU58816 (CVE-2021-44228) in certain
non-default configurations. A remote attacker with control over Thread
Context Map (MDC) input data when the logging configuration uses a
non-default Pattern Layout with either a Context Lookup (for example,
$${ctx:loginId}) or a Thread Context Map pattern (%X, %mdc, or %MDC) can
pass malicious data using a JNDI Lookup pattern and perform a denial of
service (DoS) attack, exfiltrate data or execute arbitrary code.
Later discovery demonstrates a remote code execution on macOS but no other tested environments.

2) Code Injection
EUVDB-ID: #VU58816
Risk: Critical
CVSSv4.0: 9.3 [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:A/U:Red]
CVE-ID: CVE-2021-44228
CWE-ID:
CWE-94 - Improper Control of Generation of Code ('Code Injection')
Exploit availability: Yes
DescriptionThe vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to improper input validation when processing LDAP requests. A remote attacker can send a specially crafted request to the application and execute arbitrary code on the target system.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
Note, we are aware of attackers exploiting the vulnerability in the wild.
