CVE-2026-85439

MOOS-IvP through 24.8.1 alogsplit Command Injection via Input Pathname

Published Sep 3, 2026 CVSS 4.0 · 8.5 High EPSS < 1% KEV · Not listed

Description

MOOS-IvP through 24.8.1 contains a remote code execution vulnerability in alogsplit's SplitHandler::handlePreCheckSplitDir() function that fails to sanitize shell metacharacters in log file pathnames. Attackers can embed shell syntax in log file names or the --dir parameter to execute arbitrary commands with the privileges of the operator running alogsplit.

Analysis

Technical impact

MOOS‑IvP through version 24.8.1 has a remote code execution vulnerability in the alogsplit utility. The SplitHandler::handlePreCheckSplitDir() function does not sanitize shell metacharacters embedded in log file names or in the --dir parameter, allowing an attacker to inject arbitrary shell commands that will execute with the privileges of the user running alogsplit.

Affected Systems

All installations of MOOS‑IvP version 24.8.1 and earlier are vulnerable. The flaw resides in the alogsplit LogHandler component of the MOOS‑IvP package.

Risk and Exploitability

The CVSS score of 8.5 indicates a high‑severity risk. EPSS data is unavailable, so the exact likelihood of exploitation cannot be quantified. Attacks require the attacker to provide a malicious log filename or --dir argument when alogsplit is run, and the vulnerability is not listed in the CISA KEV catalog, suggesting no known widespread exploitation to date. Nonetheless, the potential for an attacker to execute arbitrary commands remains significant.

Affected Products

Default status is the baseline for the product, each version can override it (e.g. patched versions marked unaffected).

Remediation

No solution or workaround provided in the CVE record.

OpenCVE Recommended Actions

Upgrade MOOS‑IvP to a release newer than 24.8.1 that includes the fixed alogsplit handler.
When an upgrade cannot be performed immediately, limit the use of alogsplit to a controlled environment: ensure that any log filenames or directory arguments are generated only by trusted sources and that shell metacharacters are escaped or rejected before the command is constructed.
Run alogsplit under the least‑privileged account possible and monitor its execution for unexpected command invocations or anomalous file creation.
