CVE-2017-9580

20
FAUCET Score

CVE-2017-9580 describes a critical vulnerability in the "Pioneer Bank & Trust Mobile Banking" iOS application (version 3.0.0) where it fails to properly validate X.509 certificates from SSL servers. This oversight allows man-in-the-middle attackers to spoof legitimate servers using a crafted certificate, potentially leading to the interception of sensitive user information. Rated with a CVSS score of 5.9 (Medium), this vulnerability has a network attack vector and high confidentiality impact, but requires high attack complexity. While the EPSS score is low, indicating a low probability of exploitation, the potential for data theft is significant if successfully leveraged. Currently, there is no evidence of active exploitation, nor is there publicly available exploit code in Metasploit, Nuclei, or ExploitDB. The vulnerability has garnered no community discussion or media coverage, suggesting a low level of awareness or attention.
