Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-48687 in the wild and no public exploit code.\n\nAffected product: n/a. No package-level version data is available, so check the vendor advisory linked from the reference page.\n\nTask:\n1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.\n2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.\n3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.\n4. Run the tests and summarise what changed and why.\n5. If nothing in the project is affected, say so and change nothing.\n\nReference: https://insights.sbomify.com/CVE-2026-48687/ (Markdown: https://insights.sbomify.com/CVE-2026-48687/index.md)","id":"CVE-2026-48687","markdown":"https://insights.sbomify.com/CVE-2026-48687/index.md","name":"CVE-2026-48687","record":{"aliases":["DEBIAN-CVE-2026-48687","GHSA-qx97-6jw5-h44w","UBUNTU-CVE-2026-48687"],"analysis":{"component_type":"server_software","fix_type":"patch","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"Network monitoring software","requires_auth":"low_privilege","summary":"Attackers can execute arbitrary OS commands via unsanitized input in the Juniper router integration plugin of FastNetMon Community Edition.","user_interaction":"not_required","vuln_class":"command_injection"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"fastnetmon","vendor":"pavel-odintsov"}],"cvss":{"score":8.1,"severity":"high","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:N","version":"3.1"},"cwes":[{"id":"CWE-78","name":"Improper Neutralization of Special Elements used in an OS Command"}],"description":"FastNetMon Community Edition through 1.2.9 contains an OS command injection vulnerability in the Juniper router integration plugin. The _log() function in src/juniper_plugin/fastnetmon_juniper.php (lines 117-118) constructs shell commands by concatenating the $msg parameter directly into exec() calls: exec(\"echo `date` \\\"- {FASTNETMON] - \" . $msg . \" \\\" \u003e\u003e \" . $FILE_LOG_TMP). The $msg variable contains unsanitized data derived from command-line arguments argv[1] through argv[3], which represent the attack IP address, direction, and power. While FastNetMon's C++ core currently passes IP addresses via inet_ntoa() (which only produces safe dotted-decimal notation), the PHP script performs no input validation or shell escaping. If the script is invoked directly, by another orchestration system, or if future code changes pass string-sourced IPs, arbitrary commands can be injected. The correct fix is to replace exec() with file_put_contents() or use escapeshellarg() on all parameters.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":true,"headline":"Command injection in n/a","id":"CVE-2026-48687","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"command_injection","year":"2026"},"n_packages":0,"n_references":3,"next":{"headline":"Memory corruption in n/a","id":"CVE-2026-48688"},"packages":[],"prev":{"headline":"Memory corruption in n/a","id":"CVE-2026-48686"},"products":["n/a"],"published":"2026-05-26","related":[{"cvss_score":9.8,"headline":"Memory corruption in n/a","id":"CVE-2026-48686","kev_date_added":null,"published":"2026-05-26"},{"cvss_score":9.8,"headline":"Memory corruption in n/a","id":"CVE-2026-48689","kev_date_added":null,"published":"2026-05-26"},{"cvss_score":8.1,"headline":"Missing authorization in n/a","id":"CVE-2026-48692","kev_date_added":null,"published":"2026-05-26"},{"cvss_score":8.1,"headline":"Command injection in n/a","id":"CVE-2026-48694","kev_date_added":null,"published":"2026-05-26"},{"cvss_score":8.1,"headline":"Command injection in n/a","id":"CVE-2026-48695","kev_date_added":null,"published":"2026-05-26"},{"cvss_score":7.5,"headline":"Memory corruption in n/a","id":"CVE-2026-48688","kev_date_added":null,"published":"2026-05-26"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"US public information, NVD API terms","name":"NVD"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"no","exploitation":"none","technical_impact":"total"},"state":"PUBLISHED","updated":"2026-05-27","vendors":["n/a"]},"summary":"Attackers can execute arbitrary OS commands via unsanitized input in the Juniper router integration plugin of FastNetMon Community Edition.","url":"https://insights.sbomify.com/CVE-2026-48687/"}
