Threat & Defense Details
Likely Mitigating ControlsAI
Per-CVE control mapping for this CVE has not run yet; the list below is derived from the weakness types (CWEs) cited in the NVD entry.
Audit policy requires defining and implementing logging of security-relevant events, directly reducing insufficient logging.
Providing proof of performed actions necessitates sufficient logging of security-relevant events with attribution details.
Retaining audit records for a defined period ensures security-relevant events remain available for after-the-fact investigations, directly mitigating the risk that attackers can hide actions due to missing or purged log data.
Directly requires generation of audit records for specified events, preventing the absence of logging that allows undetected malicious activity.
Directly implements detailed session logging to address the weakness of insufficient logging.
Provides alternate logging mechanism to maintain audit trails when primary capability fails, directly reducing insufficient logging.
Employing coordination mechanisms ensures consistent and sufficient logging practices are applied when audit information crosses organizational boundaries.
This control requires identifying, specifying, and justifying event types for logging with a focus on adequacy for post-incident investigations, directly mitigating insufficient logging.
MITRE ATT&CK Enterprise TechniquesAI
Why these techniques?
Insufficient logging enables undetected information tampering (integrity impact), directly aligning with data manipulation.
NVD Description
Dell PowerScale OneFS, versions prior 9.13.0.0, contains an insufficient logging vulnerability. An unauthenticated attacker with remote access could potentially exploit this vulnerability, leading to information tampering.
Deeper analysisAI
CVE-2026-22279 is an insufficient logging vulnerability (CWE-778) in Dell PowerScale OneFS versions prior to 9.13.0.0. This flaw allows potential information tampering due to inadequate logging mechanisms.
An unauthenticated attacker with remote network access can exploit the vulnerability, which has low attack complexity but requires user interaction. Exploitation leads to low-impact integrity violations, enabling limited tampering with information, with no impact on confidentiality or availability. The CVSS v3.1 base score is 4.3 (AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:L/A:N).
Dell's security advisory DSA-2026-049 addresses this vulnerability along with others in PowerScale OneFS, recommending an update to version 9.13.0.0 or later for mitigation.
