Security readout for executives and security teams
Plain-English summary
Evernote versions before 5.5.1 stored the app PIN insecurely, weakening PIN-based protection. The risk is mainly unauthorized local access to notes when a device, profile, or app data is accessible. The source bundle does not show active exploitation.
Executive priority
Treat this as a legacy mobile data-protection issue, not an enterprise-wide remote compromise signal. Prioritize if Evernote held sensitive business data or old mobile installations remain in use.
Technical view
CVE-2013-5112 describes insecure PIN storage in Evernote before 5.5.1. A cited advisory title references Evernote Android and bypass of PIN protection. No CVSS, CWE, complete affected CPEs, or vendor remediation text is included in the bundle.
Likely exposure
Exposure is likely limited to legacy Evernote installations before 5.5.1, especially Android based on the advisory title. Organizations with managed mobile fleets or stored sensitive notes should verify whether any old app versions remain.
Exploitation context
The bundle does not cite KEV status or active exploitation. The issue appears to require access to local app/device data rather than remote network access, but exact prerequisites are not fully documented in the provided sources.
Researcher notes
Evidence is thin: the CVE record gives a minimal description, no CVSS, no CWE, and no detailed affected configuration. The Android scope is inferred from the cited advisory title, not from structured CVE affected data.
Mitigation direction
- Inventory Evernote app versions and flag installations earlier than 5.5.1.
- Upgrade Evernote to a vendor-supported current release.
- Check Evernote or platform vendor guidance for official remediation details.
- Review exposed notes for credentials, tokens, or regulated data.
- Rotate sensitive secrets that may have been stored in affected notes.
Validation and detection
- Confirm deployed Evernote versions are 5.5.1 or later.
- Check mobile device management inventory for unmanaged legacy Evernote apps.
- Review lost, shared, rooted, or forensically accessed devices for added risk.
- Verify sensitive note handling policies do not rely only on app PINs.
