CVE-2017-15906

CVSS v2.0

7.8

Alta

VetorAV:N/AC:L/Au:N/C:N/I:N/A:C
Name of the Vulnerable Software and Affected Versions OpenSSH versions prior to 7.6
Description The issue is related to the process open function in sftp-server.c, which does not properly prevent write operations when in readonly mode. This allows attackers to create zero-length files, potentially leading to a denial of service.
Recommendations For versions prior to 7.6, update to version 7.6 or later to resolve the issue. As a temporary workaround, consider restricting write operations in readonly mode to minimize the risk of exploitation.
