Zoom Patches High-Risk Flaws on Windows Platforms and its Client SDK
In a world heavily reliant on digital communications, we’re all surfers riding the wave of technology. One of the boards we trust is Zoom, a versatile platform offering myriad services such as video communications, messaging, voice calls, virtual events, and much more. Despite its many benefits, recent revelations highlight some vulnerabilities in the system that have been silent undercurrents, threatening to unseat us from our boards.
Our first encounter is CVE-2023-34116, an instance of improper input validation in Zoom’s Desktop Client for Windows before version 5.15.0. This insidious issue could let an unauthorized user turn seemingly harmless inputs into stepping stones, escalating their privileges via network access. The antidote to this threat is a simple download or update of the Zoom software, available at https://zoom.us/download.
Next, we turn our attention to CVE-2023-34117, a case of relative path traversal in Zoom’s Client SDK before version 5.15.0. This vulnerability creates a hidden pathway, allowing an unauthorized user to access confidential information via local access. The best defense against this loophole is, once again, to keep your Zoom software up to date.
The following two vulnerabilities, CVE-2023-34118 and CVE-2023-36537, concern improper privilege management in Zoom Rooms before version 5.14.5. They offer authenticated users a chance to ascend the ranks, potentially escalating their privileges via local access. To protect your digital kingdom from this internal uprising, keep your Zoom software in its latest version.
We move on to CVE-2023-34119 and CVE-2023-36536, issues tied to insecure temporary files and untrusted search paths in the installer for Zoom Rooms before version 5.15.0. These vulnerabilities offer authenticated users a map to power, escalating their privileges via local access. To guard your treasure, ensure your Zoom Rooms are updated to the latest secure versions.
Our final encounter is CVE-2023-36538, a case of improper access control in Zoom Rooms before version 5.15.0. This issue opens an unlocked door to authenticated users, allowing them an easy escalation of privileges via local access. The best lock for this door? Regular updates of your Zoom software.
