Description
This security bulletin contains information about 4 secuirty vulnerabilities.
1) Buffer overflow (CVE-ID: CVE-2024-27817)
The vulnerability allows a local application to escalate privileges on the system.
The vulnerability exists due to a boundary error in CoreMedia. A local application can trigger memory corruption and execute arbitrary code with kernel privileges.
2) Buffer overflow (CVE-ID: CVE-2024-27818)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to a boundary error within the OS kernel. A remote attacker can trigger memory corruption and execute arbitrary code on the target system.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
3) Server-Side Request Forgery (SSRF) (CVE-ID: CVE-2025-27817)
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.
4) Deserialization of Untrusted Data (CVE-ID: CVE-2025-27818)
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.
