Vulnerability Data
Due to improper TLS certificate validation in the DeskTime Time Tracking App before version 1.3.674, attackers who can position themselves in the network path between the client and the DeskTime update servers can return a malicious executable in response to…

Control response
Mitigating Controls (NIST 800-53 r5) AI
Directly requires cryptographic integrity protection for client-server update traffic, blocking the MITM delivery of malicious executables that exploits missing TLS validation.
Mandates cryptographic verification of software integrity before execution, directly countering the CWE-494 download of unvalidated update code.
Requires signed components with verification, addressing the root cause of improper certificate validation (CWE-295/296) during app updates.
Mitigating Controls (NIST CSF 2.0) AI
Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→CSF cross-walk (authority under review) — links open the control.
Directly requires assessing authenticity/integrity of software before acquisition and use, preventing unverified downloads.
Certificate-based authentication of users/services/hardware directly depends on correct validation.
Proper certificate validation is a core mechanism for protecting data-in-transit confidentiality and integrity.
Prevents execution of unauthorized software, blocking the outcome of an unchecked download.
Secure development practices explicitly include implementing correct certificate validation logic.
Identity assertions conveyed via certificates require validation to be verified.
Mitigating Controls (ISO/IEC 27001:2022 Annex A) AI
Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→ISO cross-walk (authority under review) — links open the control.
Mandates proper use of cryptography including certificate validation and trusted roots.
Security testing can detect missing or incorrect certificate chain validation.
Mandating integrity checks, digital signatures, and origin tracing for ICT components directly reduces the chance that code or firmware lacking an integrity check will be accepted into the organisation’s environment.
Secure coding standards address correct certificate chain validation.
Requires secure authentication mechanisms that rely on valid certificate chains.
Network security controls often enforce TLS certificate validation.
