CISA Malcolm
Successful exploitation of these vulnerabilities could allow an attacker to cause a denial-of-service condition or execute arbitrary code.

Medium 5.4
Incorrect Authorization in 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, /admin_login, /arkime/api/esadmin, NetBox, upload endpoints) by pattern-matching the raw, percent-encoded …

Medium 6.5
Improper Handling of Highly Compressed Data in Malcolm
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 …
-
High 7.1
Cross-Site Request Forgery in Malcolm
The Malcolm kiosk Flask application exposes a POST /script_call/<script> endpoint with zero authentication and wildcard CORS (CORS(app)). An attacker can force the operator's browser to execute arbitrary management commands via CSRF, including control.py --wi…

Medium 4.2
Authentication Bypass Using an Alternate Path or Channel in Malcolm
The Arkime live capture service (arkime-live) in Malcolm runs with network_mode: host, exposing port 8005 on all network interfaces (viewHost=0.0.0.0). Arkime trusts the X-Forwarded-User header from any IP address (userAuthIps=::,0.0.0.0/0) and auto-creates u…

High 7.1
Server-Side Request Forgery in Malcolm
The bundled FilePond PHP server in Malcolm's file-upload component exposes a fetch route that retrieves an arbitrary URL and returns the response to the caller. An authenticated user can exploit this server-side request forgery (SSRF) to read HTTP, HTTPS, or …
-
High 8.1
Incorrect Authorization in Malcolm
Malcolm's nginx based reverse proxy contains a URL path normalization inconsistency between its Lua based role-based access control (RBAC) authorization layer and nginx's own request routing logic. An authenticated user can craft a specially formatted request…
-
Medium 6.5
Authentication Bypass by Spoofing in Malcolm
Malcolm's front nginx reverse proxy defines a "Dashboards → Arkime shortcut" location using a case-insensitive regex matcher but a case-sensitive rewrite. A request whose path segment is not exact-lowercase (for example /IDDASH2ARK/...) enters the location (t…

The administrative password is hashed using a comparatively weak, fast algorithm for the credential store backing one a…

High 8.1
Use of default credentials in Malcolm
An example environment-configuration file for a bundled inventory-management component ships with a fixed, publicly-known administrative password. A deployment that copies this example file into active configuration without running the setup routine that rege…
-
Low 3.7
Dependency on vulnerable third-party component in Malcolm
A prior update that raised a bundled HTTP client library to a version remediating known vulnerabilities was later reverted, reintroducing the earlier, vulnerable version into a log-processing component. The only code path in that component using the library i…
-
Medium 4.3
Missing authorization in Malcolm
A deployment mode intended to expose only read access to a bundled packet-analysis component's interface denies a list of write-capable routes by pattern, but the pattern omits routes that modify tags attached to stored session records, and the proxy configur…
-
Low 3.5
Open Redirect in Malcolm
A file-upload handler redirects the authenticated client's browser to a URL taken directly from that same request's Referer header, without validating it against the application's own origin. This allows an authenticated attacker to craft a request that cause…
-
Medium 5.3
Improper certificate validation in Malcolm
Requests from the reverse proxy to the identity-provider service for token discovery, introspection, and credential exchange do not verify the identity provider's server certificate. An attacker positioned on the network path between the proxy and the identit…
-
Medium 5.9
Use of Default Credentials in Malcolm
An example environment-configuration file ships with a fixed, publicly-known secret value used to sign authentication cookies for a bundled packet-analysis component. A deployment that copies this example file into active configuration without running the set…
-
Medium 4.3
Incorrect Authorization in Malcolm
The application's role-authorization lookup defaults to granting access when a request handler's name is not present in its table of role requirements, rather than defaulting to deny. Any request handler that is not explicitly registered in this table is reac…
-
Medium 6.5
Missing Authentication for Critical Function in Malcolm
When a particular authentication mode is configured, the reverse proxy forwards requests for a bundled third-party administrative interface directly to that interface without applying the gateway's own authentication requirement first. All access control for …
-
Medium 6.5
Missing Authorization in Malcolm
A deployment mode intended to expose only read access to stored data proxies a set of application programming interface routes without restricting which request methods are allowed. One such route accepts a request that creates or overwrites a stored record, …
-
Medium 6.5
Authentication Bypass by Spoofing in Malcolm
A routing rule selects between two different authentication mechanisms for the same downstream service based on the value of a client-supplied request header, rather than on any property the client cannot control. An authenticated user in possession of a shar…
-
Medium 4.3
Server-Side Request Forgery in Malcolm
An application programming interface endpoint accepts a user-supplied value and interpolates it directly into the path of a backend request to the underlying search and analytics data store, without restricting its contents. This allows an authenticated attac…
-
Medium 6.5
Path Traversal in Malcolm
An interface that accepts file uploads from authenticated users extracts the contents of uploaded archives without validating that extracted file paths remain within the intended destination directory. This allows an authenticated attacker to craft an archive…
-
High 8.8
OS Command Injection in Malcolm
A file-transfer interface that requires valid credentials accepts attacker-controlled filenames without restricting shell metacharacters. An automated process later constructs and runs a system command using the uploaded file's name, allowing an authenticated…
-
Medium 5.4
Cross-site Scripting in Malcolm
A web interface reflects a portion of the request URL into a script context and a hyperlink attribute without adequate encoding, and does not require authentication to reach. This allows an unauthenticated network attacker to craft a link that, when visited b…
