2) Resource exhaustion

EUVDB-ID: #VU73244

Risk: Medium

CVSSv3.1: 6.5 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H/E:U/RL:O/RC:C]

CVE-ID: CVE-2023-26464

CWE-ID: CWE-400 - Resource exhaustion

Exploit availability: No

Description

The 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. When using the Chainsaw or SocketAppender components with Log4j 1.x on JRE less than 1.7, an attacker that manages to cause a logging entry involving a specially-crafted (i.e., deeply nested) hashmap or hashtable (depending on which logging component is in use) to be processed can exhaust the available memory in the virtual machine and achieve denial of service when the object is deserialized.

Mitigation

Install update from vendor's website.

3) Deserialization of Untrusted Data

EUVDB-ID: #VU59692

Risk: High

CVSSv3.1: 8.5 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H/E:U/RL:O/RC:C]

CVE-ID: CVE-2022-23302

CWE-ID: CWE-502 - Deserialization of Untrusted Data

Exploit availability: No

Description

The 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 JMSSink. A remote attacker can provide a TopicConnectionFactoryBindingName configuration causing JMSSink to perform JNDI requests and execute arbitrary code on the target system.

Note, a non-default configuration with support for JMSSink is required to exploit this vulnerability.

5) Deserialization of Untrusted Data

EUVDB-ID: #VU27960

Risk: Medium

CVSSv3.1: 7.1 [CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H/E:U/RL:O/RC:C]

CVE-ID: CVE-2019-17571

CWE-ID: CWE-502 - Deserialization of Untrusted Data

Exploit availability: No

Description

The 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 within the SocketServer class in Log4j. A remote attacker can pass specially crafted data to the application and execute arbitrary code on the target system,  if these is a deserialization gadget listening to untrusted network traffic for log data.

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

Mitigation

Install update from vendor's website.

6) SQL injection

EUVDB-ID: #VU59691

Risk: Medium

CVSSv3.1: 6.4 [CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:N/E:U/RL:O/RC:C]

CVE-ID: CVE-2022-23305

CWE-ID: CWE-89 - Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection')

Exploit availability: No

Description

The vulnerability allows a remote attacker to execute arbitrary SQL queries in database.

The vulnerability exists due to insufficient sanitization of user-supplied data in the JDBCAppender. A remote attacker can send a specially crafted request to the affected application and execute arbitrary SQL commands within the application database.

Note, a non-default configuration with enabled JDBCAppender is required to exploit the vulnerability.

7) Deserialization of Untrusted Data

EUVDB-ID: #VU58977

Risk: Medium

CVSSv3.1: 7.1 [CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H/E:U/RL:O/RC:C]

CVE-ID: CVE-2021-4104

CWE-ID: CWE-502 - Deserialization of Untrusted Data

Exploit availability: No

Description

The 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.

Mitigation

Install update from vendor's website.
