CVE-2017-5589

18
FAUCET Score

CVE-2017-5589 describes a user impersonation vulnerability in XMPP clients yaxim and Bruno (versions 0.8.6 - 0.8.8 for Android). This flaw stems from an incorrect implementation of the "XEP-0280: Message Carbons" standard, allowing a remote attacker to display messages as if they originated from any user, including legitimate contacts. The vulnerability has a CVSS v3 score of 5.9 (MEDIUM), indicating a network-based attack with high impact on integrity and high attack complexity, but no impact on confidentiality or availability. This could facilitate social engineering attacks. There is no evidence of active exploitation, nor are there publicly available exploit modules in Metasploit, Nuclei, or ExploitDB. Community discussion and media coverage are minimal, with only one mention and one article identified.
