#telnet

The telnet administrator service running on port 650 on Gigaset DX600A v41.00-175 devices does not implement any lockout or throttling functionality. This situation (together with the weak password policy that forces a 4-digit password) allows remote attackers to easily obtain administrative access via brute-force attacks.

A vulnerability has been identified in SIMATIC HMI Comfort Panels (incl. SIPLUS variants) (All versions < V16 Update 3a), SIMATIC HMI KTP Mobile Panels (All versions < V16 Update 3a), SINAMICS GH150 (All versions), SINAMICS GL150 (with option X30) (All versions), SINAMICS GM150 (with option X30) (All versions), SINAMICS SH150 (All versions), SINAMICS SL150 (All versions), SINAMICS SM120 (All versions), SINAMICS SM150 (All versions), SINAMICS SM150i (All versions). Affected devices with enabled telnet service do not require authentication for this service. This could allow a remote attacker to gain full access to the device. (ZDI-CAN-12046)

Zoho ManageEngine Applications Manager before 14 build 14880 allows an authenticated SQL Injection via a crafted Alarmview request.

An information disclosure vulnerability exists in the Web Manager and telnet CLI functionality of Lantronix XPort EDGE 3.0.0.0R11, 3.1.0.0R9, 3.4.0.0R12 and 4.2.0.0R7. A specially crafted HTTP request can cause information disclosure. An attacker can sniff the network to trigger this vulnerability.

An authentication bypass vulnerability exists in the Web Manager functionality of Lantronix XPort EDGE 3.0.0.0R11, 3.1.0.0R9, 3.4.0.0R12 and 4.2.0.0R7. A specially crafted HTTP request can cause increased privileges. An attacker can send an HTTP request to trigger this vulnerability.

Askey AP5100W_Dual_SIG_1.01.097 and all prior versions use a weak password at the Operating System (rlx-linux) level. This allows an attacker to gain unauthorized access as an admin or root user to the device Operating System via Telnet or SSH.

Improper input validation in the Auto-Discovery component of Nagios XI before 5.7.5 allows an authenticated attacker to execute remote code.

A vulnerability in the persistent Telnet/Secure Shell (SSH) CLI of Cisco IOS XE Software could allow an authenticated, local attacker to gain shell access on an affected device and execute commands on the underlying operating system (OS) with root privileges. The vulnerability is due to insufficient enforcement of the consent token in authorizing shell access. An attacker could exploit this vulnerability by authenticating to the persistent Telnet/SSH CLI on an affected device and requesting shell access. A successful exploit could allow the attacker to gain shell access on the affected device and execute commands on the underlying OS with root privileges.

D-Link COVR-2600R and COVR-3902 Kit before 1.01b05Beta01 use hardcoded credentials for telnet connection, which allows unauthenticated attackers to gain privileged access to the router, and to extract sensitive data or modify the configuration.

In coturn before version 4.5.1.3, there is an issue whereby STUN/TURN response buffer is not initialized properly. There is a leak of information between different client connections. One client (an attacker) could use their connection to intelligently query coturn to get interesting bytes in the padding bytes from the connection of another client. This has been fixed in 4.5.1.3.
