CVE-2018-19878 — An issue was discovered on Teltonika RTU950 R_31.04.89 devices

Medium CVSS 6.8

An issue was discovered on Teltonika RTU950 R_31.04.89 devices. The application allows a user to login without limitation. For every successful login request, the application saves a session. A user can re-login without logging out, causing the application to store the session in memory. Exploitation of this vulnerability will increase memory use and consume free space.

Matched remediation archetype

Use-after-free, double free, and expired resource use

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

Check exposure

  • Trace ownership, references, callbacks, asynchronous tasks, and teardown paths around the affected object or resource.
  • Identify reachable inputs and timing or state transitions that can release the object while references remain.
  • Confirm affected builds, allocators, feature flags, architectures, and process privileges.

Remediate safely

  • Apply the maintained ownership or lifetime fix and rebuild all artifacts containing the affected native code.
  • Use explicit ownership, safe reference management, cancellation and join semantics, and idempotent teardown.
  • Add deterministic lifetime tests plus isolated sanitizer and concurrency coverage for shutdown and error paths.
