Description

This security bulletin contains information about 3 vulnerabilities.


1) Server-Side Request Forgery (SSRF) (CVE-ID: CVE-2025-27817)

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

CVSSv4: 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


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.


2) Resource exhaustion (CVE-ID: CVE-2025-48976)

CWE-ID: CWE-400 - Resource exhaustion

CVSSv4: 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/E:P/U:Green


The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to Apache Commons FileUpload provided a hard-coded limit of 10kB for the size of the headers associated with a multipart request. A remote attacker can trigger resource exhaustion and perform a denial of service (DoS) attack.


3) Authorization bypass through user-controlled key (CVE-ID: CVE-2023-44981)

CWE-ID: CWE-639 - Authorization Bypass Through User-Controlled Key

CVSSv4: 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/E:U/U:Green


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.
