Malcolm Malcolm は、以下の目標を念頭に設計された強力なネットワークトラフィック解析ツールスイートです。 使いやすさ – Malcolm は、フルパケットキャプチャ PCAP ファイル、Zeek ログ、Suricata アラートの形でネットワークトラフィックデータを受け入れます。これらのアーティファクトは、シンプルなブラウザベースのインターフェースを介してアップロードするか、軽量フォワーダを使用して受動的にキャプチャして Malcolm に転送できます。いずれの場合も、データは自動的に正規化、エンリッチメント、および相関が行われ、分析に利用できるようになります。...

CVE-2026-19671

Malcolm's upload-processing pipeline scripts/safe-extract.py enforces entry-count, nesting-depth, and total-uncompressed-byte limits when extracting container archives zip/tar/rar/7z via libarchive, but those limits are not applied when the uploaded file is a single-stream compressed format .gz,...

CVE-2026-19670

Malcolm's nginx Lua role-based access control RBAC layer decides whether an authenticated user may reach a role-restricted path e.g. /htadmin, /auth, /adminlogin, /arkime/api/esadmin, NetBox, upload endpoints by pattern-matching the raw, percent-encoded request URI. Nginx itself, however, selects...

CVE-2026-19671

Malcolm's safe-extract.py enforces decompression limits only on container archives (zip/tar/rar/7z) but not on single-stream formats (.gz/.xz/.lzma/.lz). An authenticated user can upload a small gzip bomb that decompresses unboundedly, exhausting the shared Docker volume used by OpenSearch, Logst...

CVE-2026-19670 Incorrect Authorization in CISA Malcolm

Malcolm's nginx Lua role-based access control RBAC layer decides whether an authenticated user may reach a role-restricted path e.g. /htadmin, /auth, /adminlogin, /arkime/api/esadmin, NetBox, upload endpoints by pattern-matching the raw, percent-encoded request URI. Nginx itself, however, selects...

CVE-2026-19670

Malcolm's nginx Lua RBAC layer pattern-matches the raw percent-encoded URI while nginx routes using the decoded URI, allowing an authenticated low-privilege user to access admin-only paths via encoded URLs like /%68tadmin.php. CVSS 5.4 (MEDIUM); no in-the-wild exploitation reported. No patch vers...

CVE-2026-63133

Malcolm is a network traffic analysis tool suite. Prior to version 26.07.0, safe-extract.py extracts uploaded archives with no limit on entry count, directory depth, total entries, or output size. A small malicious archive containing a large number of directory or file entries causes the filebeat...

CVE-2026-63134

Malcolm is a network traffic analysis tool suite. Prior to version 26.07.0, safe-extract.py protects file extraction with libarchive's secure flags, but creates directory entries with a raw os.makedirsos.path.joindest, entry.pathname that has no traversal protection. An uploaded malicious archive...

CVE-2026-63177

Malcolm is a network traffic analysis tool suite. Prior to version 26.07.0, role-based access control enforced in the Nginx OpenResty Lua layer evaluates the raw, unnormalized ngx.var.requesturi, while Nginx itself routes requests using the normalized path. An authenticated low-privilege user can...

CVE-2026-55676

Malcolm is a network traffic analysis tool suite. The file-upload component FilePond PHP backend accepts uploads at POST /server/php/submit.php and stores them in a directory served by the same nginx and php-fpm instance. The allow-list that should restrict accepted file types is an empty array b...

CVE-2026-63177

What is affected: Malcolm (network traffic analysis tool suite). The issue is in the Nginx OpenResty Lua RBAC layer prior to v26.07.0, where RBAC evaluates the unnormalized ngx.var.request_uri while Nginx routes on the normalized path. Root cause: URI normalization mismatch allows a low-privilege...
