CVE-2026-45787 is a medium-severity Inadequate Encryption Strength (CWE-326) vulnerability in Electerm Project Electerm. Its CVSS base score is 6.0 (Medium).
Operationally, exploitation aligns with the MITRE ATT&CK technique Weaken Encryption (T1600); ranked at the 1th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog.
The strongest mitigations our analysis identified map to IA-5 (Authenticator Management) and SA-11 (Developer Testing and Evaluation) — see the control section below for these in your framework.

Vulnerability Data
electerm is an open-sourced terminal/ssh/sftp/telnet/serialport/RDP/VNC/Spice/ftp client. Prior to 3.9.5, deterministic AES-192-CBC with a fixed zero IV, constant KDF salt, and no MAC leads to confidentiality and integrity failures for synced bookmark/profile data. Attackers can crack common passwords across installs and…

Mitigating Controls (NIST 800-53 r5) AI
SC-13 requires selection and implementation of specific cryptographic algorithms and key lengths, directly preventing use of inadequate encryption strength.
SC-8 directly requires mechanisms to protect integrity of transmitted data, which structurally eliminates the missing checksum weakness in protocols.
Authenticator management requires secure credential storage practices that include salted hashes.
Developer testing and evaluation can identify missing salt values through code review or analysis.
Development standards and tools can mandate salted hashing as part of secure implementation requirements.
Engineering principles applied during design and implementation can mandate cryptographically secure IV generation.
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 integrity protection for data-in-transit via checksums or equivalent mechanisms.
Secure SDLC practices mandate correct password storage with salts, eliminating this exact weakness.
Strong encryption is required to protect confidentiality of data-at-rest.
Authentication policies may reference password handling but do not address storage or computational cost of hashes.
Hardened baselines can enforce minimum cryptographic algorithm and key-length settings.
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 cryptographic controls including IV generation, directly preventing predictable-IV CBC weaknesses.
Security testing in development can detect predictable IV usage before deployment.
Requires secure handling of authentication information, which includes choosing strong password hashing schemes.
Network security controls can mandate integrity mechanisms on transmission protocols.
Security requirements for network services can require integrity checks on data in transit.
Secure SDLC processes catch cryptographic flaws like bad IVs during design and review phases.
