CVE-2019-14889· NVD / CVE Program· CNA redhat

A flaw was found with the libssh API function ssh_scp_new() in versions before 0.9.3 and before 0.8.8.

Noroxi assessment

Priority: Monitor (action score 36/100)

The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
Probability of exploitation in the next 30 days: 3.1% (FIRST EPSS); higher than 87.9% of all records.
Anyone who can reach it over the internet can trigger it. No account or password is required. A user must open a link or visit a page. No special conditions are required; it is repeatable.
Fixed version: libssh (Alpine:v3.10) 0.8.8-r0; libssh (Alpine:v3.11) 0.9.3-r0; libssh (Alpine:v3.8) 0.7.6-r1.
Mentioned 1 time in Turkish national cyber security advisories (siberguvenlik.gov.tr).

Low priority for now. Upgrade to libssh (Alpine:v3.10) 0.8.8-r0; libssh (Alpine:v3.11) 0.9.3-r0; libssh (Alpine:v3.8) 0.7.6-r1 or later.

Generated automatically from the record's data: CVSS (NVD and CNA), CISA KEV and SSVC, FIRST EPSS, exploit sources, fixed versions. How we calculate it

Primary sources: NVD · CVE.org · FIRST EPSS

A flaw was found with the libssh API function ssh_scp_new() in versions before 0.9.3 and before 0.8.8. When the libssh SCP client connects to a server, the scp command, which includes a user-provided path, is executed on the server-side. In case the library is used in a way where users can influence the third parameter of the function, it would become possible for an attacker to inject arbitrary commands, leading to a compromise of the remote target.
