CVE-2015-4715

15
FAUCET Score

CVE-2015-4715 describes a file disclosure vulnerability in the Dropbox-PHP library, specifically within the fetch function of OAuth/Curl.php. This flaw, affecting ownCloud Server versions prior to 6.0.8, 7.0.6, and 8.0.4 when external Dropbox storage is mounted, allows remote Dropbox.com administrators to read arbitrary files by injecting an '@' character into POST values. Rated as Medium severity (CVSS 4.9), it requires high privileges (PR:H) but has low attack complexity (AC:L) and can lead to high confidentiality impact (C:H). There is no evidence of active exploitation, public exploit code (Metasploit, Nuclei, ExploitDB), or significant community discussion or media coverage.
