Security Bulletin

This security bulletin contains information about 2 vulnerabilities.

1) Deserialization of Untrusted Data

EUVDB-ID: #VU112255

Risk: Medium

CVSSv4.0: 6.3 [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/E:U/U:Green]

CVE-ID: CVE-2025-27818

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

Exploit availability: No

Description

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.

Mitigation

Install update from vendor's website.

Vulnerable software versions

2) Server-Side Request Forgery (SSRF)

EUVDB-ID: #VU112146

Risk: High

CVSSv4.0: 7.8 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:L/VA:N/SC:L/SI:L/SA:N/E:P/U:Amber]

CVE-ID: CVE-2025-27817

CWE-ID: CWE-918 - Server-Side Request Forgery (SSRF)

Exploit availability: Yes

Description

The disclosed vulnerability allows a remote attacker to perform SSRF attacks.

The vulnerability exists due to insufficient validation of user-supplied input in Apache Kafka Client. The application accepts configuration data for setting the SASL/OAUTHBEARER connection with the brokers, including "sasl.oauthbearer.token.endpoint.url" and "sasl.oauthbearer.jwks.endpoint.url". A remote attacker can send a specially crafted HTTP request and trick the application to initiate requests to arbitrary systems.

Successful exploitation of this vulnerability may allow a remote attacker gain access to sensitive data, located in the local network or send malicious requests to other servers from the vulnerable system.
