Security Bulletin
This security bulletin contains information about 4 vulnerabilities.
EUVDB-ID: #VU58977
Risk: Medium
CVSSv4.0: 7.2 [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:U/U:Green]
CVE-ID: CVE-2021-4104
CWE-ID:
CWE-502 - Deserialization of Untrusted Data
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to insecure input validation when processing serialized data in JMSAppender, when the attacker has write access to the Log4j configuration. The attacker can provide TopicBindingName and TopicConnectionFactoryBindingName configurations causing JMSAppender to perform JNDI requests that result in remote code execution.
Note this issue only affects Log4j 1.2 when specifically configured to
use JMSAppender, which is not the default.

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.

EUVDB-ID: #VU59281
Risk: High
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:Amber]
CVE-ID: CVE-2021-38951
CWE-ID:
CWE-400 - Resource exhaustion
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to application does not properly control consumption of internal resources. A remote attacker can send a specially crafted request to the web server, consume all available CPU resources and perform a denial of service (DoS) attack.

EUVDB-ID: #VU58844
Risk: High
CVSSv4.0: 6.1 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Amber]
CVE-ID: CVE-2021-4101
CWE-ID:
CWE-122 - Heap-based Buffer Overflow
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to compromise vulnerable system.
The vulnerability exists due to a boundary error when processing untrusted HTML content in Swiftshader. A remote attacker can create a specially crafted web page, trick the victim into opening it, trigger a heap-based buffer overflow and execute arbitrary code on the target system.
