Security readout for executives and security teams
Plain-English summary
Parallaxis Cuckoo Clock 5.0 has a critical memory corruption flaw in its alarm scheduling feature. If reachable, an unauthenticated attacker could potentially run code on the affected system. The available sources do not identify a vendor patch, so exposure should be quickly inventoried and reduced.
Executive priority
Treat as urgent for any environment where Cuckoo Clock 5.0 is installed. Because code execution is possible and no fix is cited, prioritize removal, isolation, or replacement over routine patch cycles.
Technical view
CVE-2020-37159 is a stack-based buffer overflow (CWE-121) in Parallaxis Cuckoo Clock 5.0 alarm scheduling. The listed CVSS 3.1 score is 9.8, with network attack vector, low complexity, no privileges, no user interaction, and high confidentiality, integrity, and availability impacts.
Likely exposure
Exposure appears limited to systems running Parallaxis Cuckoo Clock version 5.0. Business risk depends on whether the application is installed, network-reachable, and used in an environment with sensitive access or privileges.
Exploitation context
The source bundle references an ExploitDB entry, so public exploit information exists. The bundle states KEV is false, and no cited source confirms active exploitation in the wild.
Researcher notes
The evidence identifies a single affected product and version: Parallaxis Cuckoo Clock 5.0. The vulnerability is described as a stack buffer overflow in alarm scheduling. Provided sources do not include vendor remediation details or confirmed exploitation telemetry.
Mitigation direction
- Inventory endpoints for Parallaxis Cuckoo Clock 5.0 and remove it where not business-essential.
- No vendor fix is identified in provided sources; check vendor or distributor guidance.
- Restrict network exposure and untrusted input paths to the application where removal is not possible.
- Run the application with least privilege and isolate affected hosts.
- Prioritize replacement if no supported patched version is available.
Validation and detection
- Search software inventory for Parallaxis Cuckoo Clock version 5.0.
- Review endpoint telemetry for the application executable and unexpected child processes.
- Confirm whether alarm scheduling functionality is enabled or reachable in deployed use.
- Check vendor, CVE, VulnCheck, and ExploitDB references for updated remediation information.
- Document compensating controls on any host where the software remains installed.
