FAUCET Score

CVE-2021-36374 describes a denial-of-service vulnerability in Apache Ant versions prior to 1.9.16 and 1.10.11, and consequently affects products like Oracle that utilize these Ant versions. A specially crafted ZIP archive or derived formats (e.g., JAR files, office documents) can cause an Apache Ant build to allocate excessive memory, leading to an out-of-memory error and disrupting the build process. This vulnerability has a CVSS score of 5.5 (Medium), indicating a low attack complexity and requiring user interaction (e.g., opening a malicious file) to achieve high availability impact. There is no evidence of active exploitation, public exploit code (Metasploit, Nuclei, ExploitDB), or significant community discussion or media coverage regarding this CVE.
