98
FAUCET Score

CVE-2017-17562 is a critical remote code execution vulnerability affecting Embedthis GoAhead web servers prior to version 3.6.5, as well as Oracle Integrated Lights-Out Manager products. This flaw allows attackers to execute arbitrary code by manipulating untrusted HTTP request parameters when CGI is enabled and dynamically linked, specifically abusing the glibc dynamic linker's LD_PRELOAD functionality. With a CVSS score of 8.1 (HIGH), it presents a severe risk due to its network-based attack vector, low attack complexity, and high impact on confidentiality, integrity, and availability. This vulnerability is actively exploited in the wild, has publicly available exploit modules in Metasploit and Nuclei, and has garnered significant community discussion and media coverage, including its use in botnets like Gitpaste-12.
