CVE-2026-83621 1 Ntop 1 Ntopng 2026-09-21 8.1 High
ntopng is a web-based network traffic monitoring application. Prior to 6.7.260717, POST /lua/rest/v2/edit/system/edit_blacklist.lua in scripts/lua/rest/v2/edit/system/edit_blacklist.lua lacks an administrator check and calls lists_utils.editList for any authenticated user. The list_name, list_enabled, url, and list_update parameters allow a non-admin user to redirect threat-intelligence downloads to attacker-controlled content, disable blocklists, or prevent scheduled updates. The changes are persisted through Redis and reloaded without a lower-level authorization guard, undermining the integrity and availability of ntopng's threat-intelligence monitoring. This issue is fixed in version 6.7.260717.
CVE-2026-82412 1 Ntop 1 Ntopng 2026-09-21 8.8 High
ntopng is a web-based network traffic monitoring application. Prior to 6.7.260717, the vulnerability-scan endpoints scripts/lua/rest/v2/add/host/to_scan.lua and scripts/lua/rest/v2/exec/host/schedule_vulnerability_scan.lua accept the scan_ports parameter without an administrator gate and pass it through validateSingleWord, which permits shell metacharacters. scripts/lua/modules/vulnerability_scan/vs_utils.lua then concatenates scan_ports into an nmap command in nmap_scan_host and executes the command through ntop.execCmd or ntop.execCmdAsync and popen. Any authenticated non-admin user can execute operating-system commands as the ntopng process account when nmap is available. Because the endpoints accept GET requests while ntopng's CSRF validation applies to POST request bodies, an attacker can also trigger the command through a logged-in user's browser without possessing ntopng credentials. This issue is fixed in version 6.7.260717.
CVE-2026-84990 1 Ntop 1 Ntopng 2026-09-21 8.8 High
ntopng is a web-based network traffic monitoring application. Prior to 6.7.260718, scripts/lua/rest/v2/get/system/configurations/list_available_backups.lua and scripts/lua/rest/v2/get/system/configurations/download_backup.lua allow any authenticated non-admin user to list and download system-configuration backups without an administrator check. The download path reaches backup_config.export_backup, and prefs_dump_utils.build_prefs_dump_table includes the ntopng.user.* Redis key space in the backup. A downloaded backup can therefore disclose password hashes for local users and, when configured, API tokens, TOTP secrets, and WebAuthn credential data, enabling account compromise through usable or recoverable credentials. This issue is fixed in version 6.7.260718.
CVE-2026-86098 1 Ntop 1 Ndpi 2026-09-14 7.4 High
ntop nDPI versions before 6.0 contain a heap buffer overflow vulnerability in the ndpi_json_string_escape function that writes beyond caller-supplied buffer boundaries. Attackers can trigger the overflow by supplying crafted network packet data including TLS SNI, HTTP headers, or DNS names that reach the vulnerable function, causing heap corruption.
CVE-2026-86090 1 Ntop 1 Ntopng 2026-09-14 7.1 High
ntopng before 6.7.260717 fails to perform authorization checks in the delete endpoints and recipients REST v2 handlers. Authenticated non-administrator users can issue POST requests to irreversibly delete all configured notification endpoints and recipients, silencing all alerts.
CVE-2026-86091 1 Ntop 1 Ntopng 2026-09-08 7.1 High
ntopng before 6.7.260717 fails to check user privileges in the pools bulk-delete endpoint, allowing authenticated non-administrators to delete all host pools and member bindings. Attackers can issue POST requests to the delete pools endpoint to irreversibly destroy every host pool, removing traffic policy bindings and visibility restrictions that may bypass security policies.
CVE-2026-84989 1 Ntop 1 Ntopng 2026-09-03 7.1 High
ntopng is a web-based network traffic monitoring application. In versions 6.7.0 through 6.7.260717, two REST v2 endpoints that manage ntopng's tag/badge feature — `POST /lua/rest/v2/delete/tag/tag.lua` and `POST /lua/rest/v2/edit/tag/tag.lua` — perform no authorization check at all. Any authenticated user, including a non-administrator ("unprivileged") account, can delete or rename any tag in the system, including tags created by an administrator. Version 6.7.260718 contains a fix.
CVE-2026-38968 1 Ntop 1 Ntopng 2026-07-31 9.8 Critical
ntopng through 6.6 is vulnerable to Predictable Session Identifier which can lead to Session Hijacking. HTTP session identifiers in src/HTTPserver.cpp use weak time-seeded pseudo-randomness during session creation. As a result, fresh authenticated logins can receive deterministic or colliding session cookies under attacker-controlled timing.
CVE-2026-45448 1 Ntop 1 Ntopng 2026-05-14 4.3 Medium
CWE-601 URL redirection to untrusted site ('open redirect')
CVE-2009-2732 1 Ntop 1 Ntop 2026-04-23 N/A
The checkHTTPpassword function in http.c in ntop 3.3.10 and earlier allows remote attackers to cause a denial of service (NULL pointer dereference and daemon crash) via an Authorization HTTP header that lacks a : (colon) character in the base64-decoded string.
CVE-2024-53426 1 Ntop 1 Ntopng 2026-04-15 6.2 Medium
A heap-buffer-overflow vulnerability has been identified in ntopng 6.2 in the Flow::dissectMDNS function.
CVE-2020-15473 1 Ntop 1 Ndpi 2026-01-26 9.1 Critical
In nDPI through 3.2, the OpenVPN dissector is vulnerable to a heap-based buffer over-read in ndpi_search_openvpn in lib/protocols/openvpn.c.
CVE-2020-15471 1 Ntop 1 Ndpi 2026-01-26 9.1 Critical
In nDPI through 3.2, the packet parsing code is vulnerable to a heap-based buffer over-read in ndpi_parse_packet_line_info in lib/ndpi_main.c.
CVE-2025-25066 1 Ntop 1 Ndpi 2025-10-02 8.1 High
nDPI through 4.12 has a potential stack-based buffer overflow in ndpi_address_cache_restore in lib/ndpi_cache.c.
CVE-2017-7416 1 Ntop 1 Ntopng 2025-04-20 N/A
ntopng before 3.0 allows XSS because GET and POST parameters are improperly validated.
CVE-2017-5473 1 Ntop 1 Ntopng 2025-04-20 N/A
Cross-site request forgery (CSRF) vulnerability in ntopng through 2.4 allows remote attackers to hijack the authentication of arbitrary users, as demonstrated by admin/add_user.lua, admin/change_user_prefs.lua, admin/delete_user.lua, and admin/password_reset.lua.
CVE-2017-7458 1 Ntop 1 Ntopng 2025-04-20 N/A
The NetworkInterface::getHost function in NetworkInterface.cpp in ntopng before 3.0 allows remote attackers to cause a denial of service (NULL pointer dereference and application crash) via an empty field that should have contained a hostname or IP address.
CVE-2017-7459 1 Ntop 1 Ntopng 2025-04-20 N/A
ntopng before 3.0 allows HTTP Response Splitting.
CVE-2015-8368 1 Ntop 1 Ntopng 2025-04-12 N/A
ntopng (aka ntop) before 2.2 allows remote authenticated users to change the login context and gain privileges via the user cookie and username parameter to admin/password_reset.lua.
CVE-2014-4329 1 Ntop 1 Ntopng 2025-04-12 N/A
Cross-site scripting (XSS) vulnerability in lua/host_details.lua in ntopng 1.1 allows remote attackers to inject arbitrary web script or HTML via the host parameter.
