Multiple security vulnerabilities have been disclosed in Baxter's internet-connected infusion pumps used by healthcare professionals in clinical environments to dispense medication to patients. "Successful exploitation of these vulnerabilities could result in access to sensitive data and alteration of system configuration," the U.S. Cybersecurity and Infrastructure Security Agency (CISA) said in

THC-Hydra is a high quality parallelized login hacker for Samba, Smbnt, Cisco AAA, FTP, POP3, IMAP, Telnet, HTTP Auth, LDAP, NNTP, MySQL, VNC, ICQ, Socks5, PCNFS, Cisco and more. Includes SSL support, parallel scans, and is part of Nessus.

Use of hard-coded credentials for the telnet server of CentreCOM AR260S V2 firmware versions prior to Ver.3.3.7 allows a remote unauthenticated attacker to execute an arbitrary OS command.

Nagios XI before v5.8.7 was discovered to contain a cross-site scripting (XSS) vulnerability via the ajax.php script in CCM 3.1.5.

NETGEAR R6200_V2 firmware versions through R6200v2-V1.0.3.12_10.1.11 and R6300_V2 firmware versions through R6300v2-V1.0.4.52_10.0.93 allow remote authenticated attackers to execute arbitrary command via shell metacharacters in the ipv6_fix.cgi ipv6_wan_ipaddr, ipv6_lan_ipaddr, ipv6_wan_length, or ipv6_lan_length parameters.

TOTOLINK A3002R TOTOLINK-A3002R-He-V1.1.1-B20200824.0128 is vulnerable to Insecure Permissions via binary /bin/boa.

telnetd in GNU Inetutils through 2.3, MIT krb5-appl through 1.0.3, and derivative works has a NULL pointer dereference via 0xff 0xf7 or 0xff 0xf8. In a typical installation, the telnetd application would crash but the telnet service would remain available through inetd. However, if the telnetd application has many crashes within a short time interval, the telnet service would become unavailable after inetd logs a "telnet/tcp server failing (looping), service terminated" error. NOTE: MIT krb5-appl is not supported upstream but is shipped by a few Linux distributions. The affected code was removed from the supported MIT Kerberos 5 (aka krb5) product many years ago, at version 1.8.

Seiko SkyBridge MB-A100/A110 v4.2.0 and below implements a hard-coded passcode for the root account. Attackers are able to access the passcord via the file /etc/ciel.cfg.

Trendnet TEW733GR v1.03B01 contains a Static Default Credential vulnerability in /etc/init0.d/S80telnetd.sh.

It was discovered that an internal Prosody library to load XML based on libexpat does not properly restrict the XML features allowed in parsed XML data. Given suitable attacker input, this results in expansion of recursive entity references from DTDs (CWE-776). In addition, depending on the libexpat version used, it may also allow injections using XML External Entity References (CWE-611).
