CVE-2017-8941

20
FAUCET Score

CVE-2017-8941 describes a critical vulnerability in the Interval International iOS app versions 3.3 through 3.5.1, where the application fails to properly validate X.509 certificates from SSL servers. This oversight allows man-in-the-middle attackers to spoof legitimate servers using crafted certificates, potentially leading to the interception and compromise of sensitive user information. The vulnerability is rated Medium severity (CVSS 5.9) due to its high impact on confidentiality and low attack complexity, requiring no user interaction. Despite its potential for data exposure, there is no evidence of active exploitation, publicly available exploit code (Metasploit, Nuclei, ExploitDB), or significant community discussion or media coverage surrounding this CVE.
