CVE-2023-23558 — In Eternal Terminal 6.2.1, TelemetryService uses fixed paths in /tmp
Medium
CVSS 6.3
In Eternal Terminal 6.2.1, TelemetryService uses fixed paths in /tmp. For example, a local attacker can create /tmp/.sentry-native-etserver with mode 0777 before the etserver process is started. The attacker can choose to read sensitive information from that file, or modify the information in that file.

Matched remediation archetype
Path traversal, unsafe upload, and file handling
This catalog composition supplies bounded fallback guidance. Explicitly reviewed curated workflows load with the complete record below.
Check exposure
- Trace untrusted filenames, archive entries, URLs, and path segments into read, write, include, extraction, and upload operations.
- Identify filesystem roots, mount permissions, symbolic-link behavior, archive handling, and whether uploaded content is web-accessible or executable.
- Review canonicalization and containment checks across supported operating systems and storage backends.
Remediate safely
- Generate server-side storage identifiers and resolve paths beneath a fixed root using filesystem-aware containment checks.
- Reject absolute, parent-relative, alternate-separator, device, link, and archive entries that escape the intended root.
- Store uploads outside executable or served paths, validate type and size, and use private atomic temporary files.
