CVE-2021-25158

45
FAUCET Score

CVE-2021-25158 is a remote arbitrary file read vulnerability affecting several versions of Aruba Instant Access Point (IAP) products. This flaw allows an unauthenticated attacker to read arbitrary files on the affected device. With a CVSS score of 5.9 (Medium), the vulnerability has a network attack vector and high confidentiality impact, but requires high attack complexity. While there is no evidence of active exploitation in the wild or Metasploit/Nuclei modules, an ExploitDB entry (EDB-50136) suggests a potential path to Remote Code Execution, though this is not directly indicated by the CVE description. Despite this, community discussion and media coverage remain minimal.
