CVE-2017-7658

41
FAUCET Score

CVE-2017-7658 is a critical vulnerability in Eclipse Jetty Server versions 9.2.x, 9.3.x, and 9.4.x, affecting products from vendors like Debian, HP, NetApp, and Oracle. It arises from Jetty's improper handling of conflicting HTTP headers, specifically when presented with multiple content-length headers or a content-length and chunked encoding header. This flaw allows an attacker to bypass authorization mechanisms by crafting a "pipelined" request that an intermediary might misinterpret, leading to unauthorized access. With a CVSS score of 9.8 (CRITICAL), it has a high potential for impact (confidentiality, integrity, availability) and is easily exploitable over the network with low attack complexity. While there are no known active exploits, public exploit code, or significant community discussion, its high FAUCET Risk Score of 87/100 indicates a substantial threat.
