Description
This security bulletin contains information about 3 secuirty vulnerabilities.
1) Infinite loop (CVE-ID: CVE-2021-45105)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to infinite loop within the StrSubstitutor class. A remote attacker can pass specially crafted input to the application, consume all available system resources and cause denial of service conditions.
Payload example: ${${::-${::-$${::-j}}}}
2) Code Injection (CVE-ID: CVE-2021-45046)
The vulnerability allows a remote attacker to compromise the affected system.
The
vulnerability exists due to incomplete patch in Apache Log4j 2.15.0 for
a code injection vulnerability #VU58816 (CVE-2021-44228) in certain
non-default configurations. A remote attacker with control over Thread
Context Map (MDC) input data when the logging configuration uses a
non-default Pattern Layout with either a Context Lookup (for example,
$${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.
3) Code Injection (CVE-ID: CVE-2021-44228)
The 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.
