This specific vulnerability pertains to Apache Kafka and Kafka Connect, and opens the door to a potential security loophole if exploited by an attacker. The vulnerability’s severity is underscored by its CVSS Severity Score of 8.8, indicating a high level of risk to affected systems.
    This vulnerability matters because it allows for unrestricted deserialization of untrusted data or a remote code execution (RCE) vulnerability when certain gadgets are present in the classpath. This could potentially allow an attacker to execute harmful java deserialization gadget chains on the Kafka connect server, posing a significant threat to the security and integrity of the affected systems.

    Vulnerability Summary

    CVE ID: CVE-2025-27818
    Severity: High (8.8)
    Attack Vector: Network
    Privileges Required: Low
    User Interaction: Required
    Impact: Potential system compromise or data leakage

    Affected Products

    Product | Affected Versions

    Apache Kafka | 2.0.0 to 3.9.1
    Kafka Connect | 2.3.0 to 3.9.1

    How the Exploit Works

    The vulnerability is rooted in the ability of an attacker to alter configuration settings on the Kafka cluster resource or Kafka Connect worker. By setting the `sasl.jaas.config` property for any of the connector’s Kafka clients to “com.sun.security.auth.module.LdapLoginModule”, the attacker can enable the server to connect to their LDAP server. The server then deserializes the LDAP response, providing the attacker with the means to execute Java deserialization gadget chains on the Kafka connect server. Consequently, this could lead to unrestricted deserialization of untrusted data or a remote code execution (RCE) vulnerability.

    Conceptual Example Code

    Given the nature of this exploit, the vulnerability might be exploited through a simulated shell command like this:

    $ kafka-configs --alter --add-config 'sasl.jaas.config=com.sun.security.auth.module.LdapLoginModule' --entity-type brokers --entity-name 1

    In the conceptual code above, the attacker alters the Kafka Broker configuration, setting the `sasl.jaas.config` property to the problematic “com.sun.security.auth.module.LdapLoginModule”. This setting enables the server to connect to the attacker’s LDAP server, opening the door to potential Java deserialization attacks.

    Mitigation Guidance

    To mitigate this vulnerability, we recommend applying the vendor patch or using Web Application Firewall (WAF) or Intrusion Detection System (IDS) as temporary mitigation. Also, it is advisable for Kafka users to validate connector configurations and only allow trusted LDAP configurations. It is prudent to examine connector dependencies for vulnerable versions and either upgrade their connectors, upgrade that specific dependency, or remove the connectors altogether. Users can also implement their own connector client config override policy to control which Kafka client properties can be overridden directly in a connector config and which cannot.

    While specific exploit code is not available, the following pseudocode illustrates the concept behind the attack:

    def exploit(target_ip):
    # Create a socket object
    socket_obj = create_socket()
    # Construct the malicious payload
    malicious_payload = construct_payload()
    # Send the malicious payload to the target
    socket_obj.send(target_ip, malicious_payload)

    In this pseudocode, `create_socket()` is a hypothetical function that creates a socket for network communication. `construct_payload()` is a hypothetical function that constructs the malicious payload that will cause the buffer overflow. The `socket_obj.send()` method sends the malicious payload to the target device, causing the buffer overflow and potentially leading to system compromise or data leakage.

    Mitigation and Remediation

    The most effective way to mitigate this vulnerability is by upgrading the Netgear EX3705 to version 1.0.0.98.
