An attacker, with low level privileges, can exploit this vulnerability over a network without user interaction. The successful exploitation might potentially lead to system compromise or data leakage.<\/p>\n<p><strong>Conceptual Example Code<\/strong><\/p><div id=\"ameeb-19434641\" class=\"ameeb-content ameeb-entity-placement\"><div class=\"poptin-embedded\" data-id=\"f6b387694f681\"><\/div>\r\n\r\n\r\n\r\n\r\n\r\n<\/div>\n<p>The below example is a conceptual representation of how this vulnerability might be exploited:<\/p>\n<pre><code class=\"\" data-line=\"\">$ curl http:\/\/target.example.com:port\/api\/v1\/files?file_path=\/etc\/passwd<\/code><\/pre>\n<p>In this hypothetical scenario, the attacker sends a HTTP GET request to the target server, attempting to access the \/etc\/passwd file.<\/p>\n<p><strong>Mitigation Guidance<\/strong><\/p>\n<p>To mitigate this vulnerability, users are advised to apply the vendor patch available for Couchbase Server versions 7.6.4 and 7.2.7 for Windows.
