The vulnerability resides within the \u003ccode\u003evalidateAccess\u003c/code\u003e function of the \u003ccode\u003e/api/smartfilters/testexecutions\u003c/code\u003e endpoint, potentially allowing remote attackers to inject arbitrary code. This vulnerability allows for remote code execution, potentially leading to complete system compromise. The vendor was notified but did not respond. A public exploit is reportedly available, increasing the risk of exploitation. This poses a significant risk to organizations utilizing vulnerable versions of Kafka UI.\u003c/p\u003e\n\u003ch2 id=\"attack-chain\"\u003eAttack Chain\u003c/h2\u003e\n\u003col\u003e\n\u003cli\u003eAn attacker identifies a vulnerable Kafka UI instance running a version prior to 0.7.3.\u003c/li\u003e\n\u003cli\u003eThe attacker crafts a malicious HTTP request targeting the \u003ccode\u003e/api/smartfilters/testexecutions\u003c/code\u003e endpoint.\u003c/li\u003e\n\u003cli\u003eWithin the crafted request, the attacker injects malicious code into the \u003ccode\u003evalidateAccess\u003c/code\u003e function parameters.\u003c/li\u003e\n\u003cli\u003eThe Kafka UI application processes the request without proper sanitization of the injected code.\u003c/li\u003e\n\u003cli\u003eThe injected code is executed within the context of the application server.\u003c/li\u003e\n\u003cli\u003eThe attacker gains the ability to execute arbitrary commands on the server.\u003c/li\u003e\n\u003cli\u003eThe attacker establishes a persistent connection to the compromised system, potentially via a reverse shell.\u003c/li\u003e\n\u003cli\u003eThe attacker pivots to other systems or resources within the network, potentially leading to data exfiltration or other malicious activities.\u003c/li\u003e\n\u003c/ol\u003e\n\u003ch2 id=\"impact\"\u003eImpact\u003c/h2\u003e\n\u003cp\u003eSuccessful exploitation of CVE-2026-5562 can lead to arbitrary code execution on the server hosting the Provectus Kafka UI. This could allow attackers to gain complete control of the affected system, potentially leading to data breaches, service disruption, or further lateral movement within the network. Due to the public availability of a reported exploit, organizations running vulnerable versions of Kafka UI are at increased risk of attack.
