CVE-2020-35207 — An issue was discovered in the LogMein LastPass Password Manager (aka com.lastpass.ilastpass) app 4.8.11.2403 for iOS

Medium CVSS 5.7

An issue was discovered in the LogMein LastPass Password Manager (aka com.lastpass.ilastpass) app 4.8.11.2403 for iOS. The PIN authentication for unlocking can be bypassed by forcing the authentication result to be true through runtime manipulation. In other words, an attacker could authenticate with an arbitrary PIN. NOTE: the vendor has indicated that this is not an attack of interest within the context of their threat model, which excludes jailbroken devices

Matched remediation archetype

Authentication bypass and missing authentication

This catalog composition supplies bounded fallback guidance. Explicitly reviewed curated workflows load with the complete record below.

Check exposure

  • Map every affected endpoint and protocol path, including alternate ports, legacy routes, recovery flows, service accounts, and machine-to-machine access.
  • Confirm which deployments enable the affected authentication mode and whether the interface is reachable from untrusted networks.
  • Review session, token, credential, and proxy trust configuration without attempting account takeover.

Remediate safely

  • Apply the supported fix and centralize fail-closed authentication before protected request handling.
  • Remove default or embedded credentials, rotate affected secrets and sessions, and bind authentication decisions to the intended audience and channel.
  • Add negative tests for alternate routes, malformed or absent credentials, recovery flows, and proxy-derived identity.
