CVE-2017-5428

30
FAUCET Score

CVE-2017-5428 is an integer overflow vulnerability in the createImageBitmap() function, affecting Firefox ESR < 52.0.1 and Firefox < 52.0.1. This critical vulnerability (CVSS 9.8) allows for remote code execution with low attack complexity, potentially leading to complete compromise of confidentiality, integrity, and availability. While the function runs in a content sandbox, requiring a second vulnerability for full system compromise, its high FAUCET Risk Score of 92/100 indicates significant danger. There is no public exploit code available (Metasploit, Nuclei, ExploitDB), and it is not listed on the KEV catalog, suggesting it is not actively exploited. However, the vulnerability garnered substantial community discussion and media coverage, particularly following its disclosure at Pwn2Own.
