Descripción

*** Pendiente de traducción *** AIL Framework contains a server-side request forgery (SSRF) vulnerability in its crawler submission functionality. A low-privileged authenticated user with access to the crawler interface can submit an arbitrary URL for crawling without adequate validation of the destination host.<br /> <br /> <br /> The crawler can therefore be instructed to make direct HTTP(S) requests to addresses that should not be reachable by application users, including loopback addresses, RFC1918 private networks, link-local addresses, and cloud metadata services such as 169.254.169.254.<br /> <br /> <br /> Manual crawler tasks bypass the existing domain blacklist because they are assigned a non-zero priority, and ordinary IP literals are classified as web targets and fetched directly rather than through Tor or another proxy. Consequently, an attacker can use the AIL server as a network pivot to access services available from the server&amp;#39;s network context.<br /> <br /> <br /> Responses generated by these requests, including captured HTML, screenshots, and HAR data, can subsequently be accessed through the crawler interface. This makes the SSRF non-blind and may allow an attacker to disclose sensitive internal application data, service information, or cloud instance metadata and credentials.<br /> <br /> <br /> The patch introduces validation that resolves crawler destinations and rejects URLs resolving to non-global IP addresses, addressing localhost, private-network, and link-local targets.
