The \u003ccode\u003esession_token\u003c/code\u003e cookie is generated without \u003ccode\u003eSecure\u003c/code\u003e or \u003ccode\u003eSameSite\u003c/code\u003e attributes, and all administrative API endpoints under \u003ccode\u003e/api/admin/\u003c/code\u003e lack CSRF token verification or Origin-based access controls.\u003c/p\u003e\n\u003cp\u003eWhile modern browsers implement \u003ccode\u003eSameSite=Lax\u003c/code\u003e by default - which hinders cross-site POST requests - the application remains susceptible in same-origin contexts, when accessed via legacy browsers, or during Man-in-the-Middle (MitM) attacks due to the missing \u003ccode\u003eSecure\u003c/code\u003e flag. Successful exploitation enables unauthorized actors to perform high-impact operations, including executing shell commands via \u003ccode\u003e/api/admin/task/exec\u003c/code\u003e, disabling 2FA, and modifying system configurations. This vulnerability stems from inadequate middleware configuration in the underlying Gin framework implementation.\u003c/p\u003e\n\u003ch2 id=\"attack-chain\"\u003eAttack Chain\u003c/h2\u003e\n\u003col\u003e\n\u003cli\u003eAttacker identifies the target instance of the Komari management console.\u003c/li\u003e\n\u003cli\u003eAttacker crafts a malicious payload (e.g., HTML form or JavaScript fetch request) targeting a sensitive endpoint such as \u003ccode\u003e/api/admin/task/exec\u003c/code\u003e.\u003c/li\u003e\n\u003cli\u003eAttacker lures an authenticated administrative user to a malicious site or injects the payload via existing XSS vulnerabilities in the target's environment.\u003c/li\u003e\n\u003cli\u003eThe victim's browser initiates the unauthorized request to the Komari API.\u003c/li\u003e\n\u003cli\u003eThe server receives the request, including the non-secure \u003ccode\u003esession_token\u003c/code\u003e cookie, which is automatically included by the browser if the environment does not strictly enforce \u003ccode\u003eSameSite=Lax\u003c/code\u003e or if it is a same-origin request.\u003c/li\u003e\n\u003cli\u003eThe server application, lacking CSRF middleware, processes the request as legitimate, assuming it originated from the administrative interface.\u003c/li\u003e\n\u003cli\u003eThe intended administrative operation (e.g., code execution or configuration change) is performed on the server or managed nodes.\u003c/li\u003e\n\u003c/ol\u003e\n\u003ch2 id=\"impact\"\u003eImpact\u003c/h2\u003e\n\u003cp\u003eSuccessful exploitation allows attackers to bypass administrative authentication. Impacted operations include the execution of arbitrary shell commands on managed nodes, complete disabling of administrator 2FA, deletion of monitoring records, and modification of system settings. This could lead to a total compromise of the managed infrastructure and the Komari monitoring server itself.\u003c/p\u003e\n\u003ch2 id=\"recommendation\"\u003eRecommendation\u003c/h2\u003e\n\u003cp\u003ePrioritize updating the Komari package to version 0.0.0-20260609084633-98122fa4d110 or later. Ensure that webserver-level headers are configured to prevent cross-site request forgery and that the application is served exclusively over HTTPS with cookies flagged as \u003ccode\u003eSecure\u003c/code\u003e and \u003ccode\u003eSameSite=Strict\u003c/code\u003e. For detection engineering, monitor webserver access logs for anomalous POST requests to \u003ccode\u003e/api/admin/\u003c/code\u003e paths that do not originate from the expected internal management source IPs or authorized referrers.\u003c/p\u003e\n","date_modified":"2026-09-10T00:51:29Z","date_published":"2026-09-10T00:51:29Z","id":"https://feed.craftedsignal.io/briefs/2026-09-komari-csrf/","summary":"The Komari management interface lacks CSRF protections and secure cookie attributes, allowing an attacker to perform unauthorized administrative actions including arbitrary code execution.","title":"CSRF Vulnerability in Komari Management Interface","url":"https://feed.craftedsignal.io/briefs/2026-09-komari-csrf/"}],"language":"en","title":"CraftedSignal Threat Feed - Komari (\u003c 0.0.0-20260609084633-98122fa4d110)","version":"https://jsonfeed.org/version/1.1"}
