Raw vector
CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:C/C:L/I:N/A:NSummary
CVE-2025-48929 is a medium-severity Insecure Storage of Sensitive Information (CWE-922) vulnerability in Smarsh Telemessage. Its CVSS base score is 4.0 (Medium).
Operationally, exploitation aligns with the MITRE ATT&CK technique Unsecured Credentials (T1552); ranked at the 21th 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 AC-12 (Session Termination) and AC-3 (Access Enforcement) — see the control section below for these in your framework.

Mitigating Controls (NIST 800-53 r5) AI
AC-12 directly requires automatic session termination after a defined period, structurally preventing reuse of expired session identifiers.
Enforces approved authorizations for logical access to stored information, directly stopping unauthorized read/write.
Requires protection of confidentiality/integrity for information at rest, directly addressing insecure storage.
Limits privileges so only authorized accesses to sensitive stored data are permitted.
Associates security attributes with information to support proper access decisions on storage.
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.
Credential lifecycle management directly includes enforcing session expiration to prevent reuse.
Enforces least-privilege permissions and authorization reviews that limit read/write access to stored sensitive data.
Directly protects data-at-rest confidentiality via encryption or access controls that prevent unauthorized reads.
Authentication mechanisms can incorporate session timeout checks but do not inherently address expiration policy.
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.
Secure reuse and disposal procedures, including cryptographic wiping and physical destruction, stop the insecure storage of sensitive data on media that may later be accessed by unauthorized actors.
Mandating secure disposal techniques stops the insecure retention of sensitive information on storage media that leaves organizational control.
Automatic termination of inactive sessions and limits on connection duration shrink the window during which a hijacked or unattended authenticated session can be exploited.
