CVE-2024-25729 2026-04-15 N/A 8.8 HIGH
Arris SBG6580 devices have predictable default WPA2 security passwords that could lead to unauthorized remote access. (They use the first 6 characters of the SSID and the last 6 characters of the BSSID, decrementing the last octet.)
CVE-2025-67513 2026-04-15 N/A N/A
FreePBX Endpoint Manager is a module for managing telephony endpoints in FreePBX systems. Versions prior to 16.0.96 and 17.0.1 through 17.0.9 have a weak default password. By default, this is a 6 digit numeric value which can be brute forced. (This is the app_password parameter). Depending on local configuration, this password could be the extension, voicemail, user manager, DPMA or EPM phone admin password. This issue is fixed in versions 16.0.96 and 17.0.10.
CVE-2025-5022 2026-04-15 N/A 6.5 MEDIUM
Weak Password Requirements vulnerability in Mitsubishi Electric Corporation photovoltaic system monitor “EcoGuideTAB” PV-DR004J all versions and PV-DR004JA all versions allows an attacker within the Wi-Fi communication range between the units of the product (measurement unit and display unit) to derive the password from the SSID. In addition, if the product is configured to enable the individual air conditioner control function, an attacker who has access to the Wi-Fi communication between the units by exploiting this vulnerability may be able to execute ECHONET Lite commands to perform operations such as turning the air conditioner on or off and changing the set temperature. The individual air conditioner control function is available only in display unit version 02.00.01 or later and measurement unit version 02.03.01 or later. The affected products discontinued in 2015, support ended in 2020.
CVE-2025-34058 2026-04-15 N/A N/A
Hikvision Streaming Media Management Server v2.3.5 uses default credentials that allow remote attackers to authenticate and access restricted functionality. After authenticating with these credentials, an attacker can exploit an arbitrary file read vulnerability in the /systemLog/downFile.php endpoint via directory traversal in the fileName parameter. This exploit chain can enable unauthorized access to sensitive system files.
CVE-2022-39997 2026-04-15 N/A 8.0 HIGH

CVE-2024-51398 2026-04-15 N/A 6.5 MEDIUM
Altai Technologies Ltd Altai X500 Indoor 22 802.11ac Wave 2 AP web Management Weak password leakage in the background may lead to unauthorized access, data theft, and network attacks, seriously threatening network security.
CVE-2026-25715 2026-04-15 N/A 9.8 CRITICAL
The web management interface of the device allows the administrator username and password to be set to blank values. Once applied, the device permits authentication with empty credentials over the web management interface and Telnet service. This effectively disables authentication across all critical management channels, allowing any network-adjacent attacker to gain full administrative control without credentials.
CVE-2025-9964 2026-04-15 N/A N/A
No password for the root user is set in Novakon P series. This allows phyiscal attackers to enter the console easily. This issue affects P series: P – V2001.A.C518o2 until P-2.0.05 Build 2026.02.06 (commit d0f97fd9).
CVE-2025-25211 2026-04-15 N/A 9.8 CRITICAL
Weak password requirements issue exists in CHOCO TEI WATCHER mini (IB-MCT001) all versions. If this issue is exploited, a brute-force attack may allow an attacker unauthorized access and login.
CVE-2025-55299 2026-04-15 N/A 9.4 CRITICAL
VaulTLS is a modern solution for managing mTLS (mutual TLS) certificates. Prior to 0.9.1, user accounts created through the User web UI have an empty but not NULL password set, attackers can use this to login with an empty password. This is combined with that fact, that previously disabling the password based login only effected the frontend, but still allowed login via the API. This vulnerability is fixed in 0.9.1.
