Description
This security bulletin contains information about 10 vulnerabilities.
1) Deserialization of Untrusted Data (CVE-ID: CVE-2022-23302)
CWE-ID: CWE-502 - Deserialization of Untrusted Data
CVSSv4: 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]
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.
2) SQL injection (CVE-ID: CVE-2022-23305)
CWE-ID: CWE-89 - Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection')
CVSSv4: 9.1 [CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:H/VI:H/VA:N/SC:N/SI:N/SA:N]
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.
3) Deserialization of Untrusted Data (CVE-ID: CVE-2020-9493)
CWE-ID: CWE-502 - Deserialization of Untrusted Data
CVSSv4: 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]
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. A remote attacker can pass specially crafted data to the application and execute arbitrary code on the target system.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
4) Deserialization of Untrusted Data (CVE-ID: CVE-2023-25194)
CWE-ID: CWE-502 - Deserialization of Untrusted Data
CVSSv4: 7.5 [CVSS:4.0/AV:N/AC:L/AT:P/PR:H/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N]
The vulnerability allows a remote user to execute arbitrary code on the target system.
The vulnerability exists due to Apache Kafka Connect performs deserialization of data retrieved from the configured LDAP server in "com.sun.security.auth.module.JndiLoginModule". A remote user ability to create/modify connectors on the server with an arbitrary Kafka client SASL JAAS config can configure the server to connect to a malicious LDAP server and execute arbitrary Java code on the system.
5) Authorization bypass through user-controlled key (CVE-ID: CVE-2023-44981)
CWE-ID: CWE-639 - Authorization Bypass Through User-Controlled Key
CVSSv4: 9.1 [CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:H/VI:H/VA:N/SC:N/SI:N/SA:N]
The vulnerability allows a remote attacker to bypass authorization process.
The vulnerability exists due to improper implementation of SASL Quorum Peer authentication. The instance part in SASL authentication ID, which is listed in zoo.cfg server
list, is optional and if it's missing,
the authorization check will be skipped. As a
result an arbitrary endpoint could join the cluster and begin
propagating counterfeit changes to the leader, essentially giving it
complete read-write access to the data tree.
6) Information disclosure (CVE-ID: CVE-2024-31141)
CWE-ID: CWE-200 - Exposure of sensitive information to an unauthorized actor
CVSSv4: 7.1 [CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:H/VI:L/VA:N/SC:N/SI:N/SA:N]
The vulnerability allows a remote user to escalate privileges within the application.
The vulnerability exists due to the way Apache Kafka Clients handles custom configurations. A remote user with access to REST API can read arbitrary files and variables on the system and escalate their privileges filesystem/environment access.
7) Improper authentication (CVE-ID: CVE-2024-56128)
CWE-ID: CWE-287 - Improper Authentication
CVSSv4: 9.1 [CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:H/VI:H/VA:N/SC:N/SI:N/SA:N]
The vulnerability allows a remote attacker to bypass authentication process.
The vulnerability exists due to an error in Salted Challenge Response Authentication Mechanism (SCRAM) implementation. The application does not verify that the nonce sent by the client in the second message matches the nonce sent by the server in its first message. A remote attacker with access to plain text SCRAM authentication exchange can bypass forge the second once and gain unauthorized access to the application.
8) Deserialization of Untrusted Data (CVE-ID: CVE-2025-27818)
CWE-ID: CWE-502 - Deserialization of Untrusted Data
CVSSv4: 8.7 [CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N]
The vulnerability allows a remote user to execute arbitrary code on the target system.
The vulnerability exists due to insecure input validation when processing serialized data. A remote user can set the sasl.jaas.config property for connector's Kafka clients to 'com.sun.security.auth.module.LdapLoginModule' through various override properties (producer.override.sasl.jaas.config, consumer.override.sasl.jaas.config, or admin.override.sasl.jaas.config). This configuration enables the server to connect to an attacker's LDAP server and deserialize the LDAP response, potentially leading to the execution of java deserialization gadget chains on the Kafka connect server.
9) Deserialization of Untrusted Data (CVE-ID: CVE-2025-27819)
CWE-ID: CWE-502 - Deserialization of Untrusted Data
CVSSv4: 8.7 [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]
The vulnerability allows a remote attacker to perform a denial of service attack.
The vulnerability exists due to insecure input validation when processing serialized data. A remote attacker can pass specially crafted data to the application and perform a denial of service attack.
10) Deserialization of Untrusted Data (CVE-ID: CVE-2021-4104)
CWE-ID: CWE-502 - Deserialization of Untrusted Data
CVSSv4: 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]
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.
