CVE-2024-55550
Low · 2.7
KEV High · 67 Public exploit Ransomware CWE-22 Dec 10, 2024
Mitel MiCollab Path Traversal Vulnerability
Mitel MiCollab through 9.8 SP2 could allow an authenticated attacker with administrative privilege to conduct a local file read, due to insufficient input sanitization. A successful exploit could allow the authenticated admin attacker to access resources that are constrained to the admin access level, and the disclosure is limited to non-sensitive system information. This vulnerability does not allow file modification or privilege escalation.
CVE-2024-41713
Critical · 9.1
KEV Urgent · 83 Public exploit Ransomware CWE-22 Oct 21, 2024
Mitel MiCollab Path Traversal Vulnerability
A vulnerability in the NuPoint Unified Messaging (NPM) component of Mitel MiCollab through 9.8 SP1 FP2 (9.8.1.201) could allow an unauthenticated attacker to conduct a path traversal attack, due to insufficient input validation. A successful exploit could allow unauthorized access, enabling the attacker to view, corrupt, or delete users' data and system configurations.
CVE-2024-41710
High · 7.2
KEV High · 56 CWE-88 Aug 12, 2024
Mitel SIP Phones Argument Injection Vulnerability
A vulnerability in the Mitel 6800 Series, 6900 Series, and 6900w Series SIP Phones, including the 6970 Conference Unit, through R6.4.0.HF1 (R6.4.0.136) could allow an authenticated attacker with administrative privilege to conduct an argument injection attack, due to insufficient parameter sanitization during the boot process. A successful exploit could allow an attacker to execute arbitrary commands within the context of the system.
CVE-2022-41223
Medium · 6.8
KEV High · 62 Ransomware CWE-94 Nov 21, 2022
Mitel MiVoice Connect Code Injection Vulnerability
The Director database component of MiVoice Connect through 19.3 (22.22.6100.0) could allow an authenticated attacker to conduct a code-injection attack via crafted data due to insufficient restrictions on the database data type.
CVE-2022-40765
Medium · 6.8
KEV High · 62 Ransomware CWE-77 Nov 21, 2022
Mitel MiVoice Connect Command Injection Vulnerability
A vulnerability in the Edge Gateway component of Mitel MiVoice Connect through 19.3 (22.22.6100.0) could allow an authenticated attacker with internal network access to conduct a command-injection attack, due to insufficient restriction of URL parameters.
CVE-2022-29499
Critical · 9.8
KEV Urgent · 73 Ransomware CWE-20 Apr 25, 2022
Mitel MiVoice Connect Data Validation Vulnerability
The Service Appliance component in Mitel MiVoice Connect through 19.2 SP3 allows remote code execution because of incorrect data validation. The Service Appliances are SA 100, SA 400, and Virtual SA.
CVE-2022-26143
Critical · 9.8
KEV High · 67 Public exploit CWE-306 Mar 10, 2022
MiCollab, MiVoice Business Express Access Control Vulnerability
The TP-240 (aka tp240dvr) component in Mitel MiCollab before 9.4 SP1 FP1 and MiVoice Business Express through 8.1 allows remote attackers to obtain sensitive information and cause a denial of service (performance degradation and excessive outbound traffic). This was exploited in the wild in February and March 2022 for the TP240PhoneHome DDoS attack.
CVE-2014-0160
High · 7.5
KEV Urgent · 79 Public exploit CWE-125 Apr 7, 2014
OpenSSL Information Disclosure Vulnerability
The (1) TLS and (2) DTLS implementations in OpenSSL 1.0.1 before 1.0.1g do not properly handle Heartbeat Extension packets, which allows remote attackers to obtain sensitive information from process memory via crafted packets that trigger a buffer over-read, as demonstrated by reading private keys, related to d1_both.c and t1_lib.c, aka the Heartbleed bug.
