CWE-119Published: December 19, 2017· Updated: Jun 17, 2026

7.5

CVSS v3.1

Official Description

The Enterprise version of SyncBreeze 10.2.12 and earlier is affected by a Remote Denial of Service vulnerability. The web server does not check bounds when reading server requests in the Host header on making a connection, resulting in a classic Buffer Overflow that causes a Denial of Service.

Technical Analysis

CVE-2017-17088 can be exploited remotely over the network without requiring physical or adjacent access, significantly expanding the attack surface for threat actors.

The vulnerability requires no privileges and no user interaction, making it a prime target for automated exploitation campaigns and worm-like propagation.

A successful exploit results in availability disruption (denial of service), with a CVSS base score of 7.5.

A proof-of-concept (PoC) exploit exists for CVE-2017-17088. While not yet confirmed in active campaigns, the availability of PoC code increases exploitation risk substantially.

From a weakness classification perspective (CWE-119): Buffer overflow vulnerabilities can lead to arbitrary code execution or denial of service by corrupting adjacent memory.
