CVSS v3 7.3
ATTENTION: Exploitable remotely/low skill level to exploit/public exploits are available
Vendor: Fuji Electric
Equipment: V-Server
Vulnerabilities: Use-After Free, Untrusted Pointer Dereference, Heap-based Buffer Overflow, Out-of-Bounds Write, Integer Underflow, Out-of-Bounds Read, and Stack-based Buffer Overflow
Successful exploitation of these vulnerabilities could allow for remote code execution on the device, causing a denial of service condition or information exposure.
The following versions of V-Server, a data collection and management service, are affected:
A use after free vulnerability has been identified, which may allow remote code execution.
CVE-2018-14809 has been assigned to this vulnerability. A CVSS v3 base score of 7.3 has been calculated; the CVSS vector string is (AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:L).
Multiple untrusted pointer dereference vulnerabilities have been identified, which may allow remote code execution.
CVE-2018-14811 has been assigned to this vulnerability. A CVSS v3 base score of 7.3 has been calculated; the CVSS vector string is (AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:L).
