Buffer overflow in login in various System V based operating systems allows remote attackers to execute arbitrary commands via a large number of arguments through services such as telnet and rlogin.

Buffer overflow in the client connection routine of libDtSvc.so.1 in CDE Subprocess Control Service (dtspcd) allows remote attackers to execute arbitrary commands.

Directory traversal vulnerability in IIS 5.0 and earlier allows remote attackers to execute arbitrary commands by encoding .. (dot dot) and "\" characters twice.

ntpd security hole

Buffer overflow in ntpd ntp daemon 4.0.99k and earlier (aka xntpd and xntp3) allows remote attackers to cause a denial of service and possibly execute arbitrary commands via a long readvar argument.

Buffer overflow in Transparent Network Substrate (TNS) Listener in Oracle 8i 8.1.7 and earlier allows remote attackers to gain privileges via a long argument to the commands (1) STATUS, (2) PING, (3) SERVICES, (4) TRC_FILE, (5) SAVE_CONFIG, or (6) RELOAD.

Buffer overflow in ISAPI extension (idq.dll) in Index Server 2.0 and Indexing Service 2000 in IIS 6.0 beta and earlier allows remote attackers to execute arbitrary commands via a long argument to Internet Data Administration (.ida) and Internet Data Query (.idq) files such as default.ida, as commonly exploited by Code Red.

Buffer overflow in Internet Printing ISAPI extension in Windows 2000 allows remote attackers to gain root privileges via a long print request that is passed to the extension through IIS 5.0.

The "sa" account is installed with a default null password on (1) Microsoft SQL Server 2000, (2) SQL Server 7.0, and (3) Data Engine (MSDE) 1.0, including third party packages that use these products such as (4) Tumbleweed Secure Mail (MMS) (5) Compaq Insight Manager, and (6) Visio 2000, which allows remote attackers to gain privileges, as exploited by worms such as Voyager Alpha Force and Spida.

IIS 5.0 allows remote attackers to obtain source code for .ASP files and other scripts via an HTTP GET request with a "Translate: f" header, aka the "Specialized Header" vulnerability.

security flaw

The lreply function in wu-ftpd 2.6.0 and earlier does not properly cleanse an untrusted format string, which allows remote attackers to execute arbitrary commands via the SITE EXEC command.

The Mixed Mode authentication capability in Microsoft SQL Server 7.0 stores the System Administrator (sa) account in plaintext in a log file which is readable by any user, aka the "SQL Server 7.0 Service Pack Password" vulnerability.

guestbook.pl cleanses user-inserted SSI commands by removing text between "<!--" and "-->" separators, which allows remote attackers to execute arbitrary commands when guestbook.pl is run on Apache 1.3.9 and possibly other versions, since Apache allows other closing sequences besides "-->".

Land IP denial of service.

phf CGI program allows remote command execution through shell metacharacters.

nodejs: CONTINUATION frames DoS

An attacker can make the Node.js HTTP/2 server completely unavailable by sending a small amount of HTTP/2 frames packets with a few HTTP/2 frames inside. It is possible to leave some data in nghttp2 memory after reset when headers with HTTP/2 CONTINUATION frame are sent to the server and then a TCP connection is abruptly closed by the client triggering the Http2Session destructor while header frames are still being processed (and stored in memory) causing a race condition.

Sawtooth Software Lighthouse Studio < 9.16.14 Pre-Authentication RCE

A template injection vulnerability exists in Sawtooth Software’s Lighthouse Studio versions prior to 9.16.14 via the  ciwweb.pl http://ciwweb.pl/  Perl web application. Exploitation allows an unauthenticated attacker can execute arbitrary commands.

Linksys Routers E/WAG/WAP/WES/WET/WRT-Series

An OS command injection vulnerability exists in various models of E-Series Linksys routers via the /tmUnblock.cgi and /hndUnblock.cgi endpoints over HTTP on port 8080. The CGI scripts improperly process user-supplied input passed to the ttcp_ip parameter without sanitization, allowing unauthenticated attackers to inject shell commands. This vulnerability was reported to be exploited in the wild by the "TheMoon" worm  in 2014 to deploy a MIPS ELF payload, enabling arbitrary code execution on the router. Additionally, this vulnerability may affect other Linksys products to include, but not limited to, WAG/WAP/WES/WET/WRT-series router models and Wireless-N access points and routers. Exploitation evidence was observed by the Shadowserver Foundation on 2025-02-06 UTC.

Shenzhen Aitemi M300 Wi-Fi Repeater OS Command Injection via Time Parameter

An unauthenticated OS command injection vulnerability exists in the Shenzhen Aitemi M300 Wi-Fi Repeater (hardware model MT02) via the 'time' parameter of the '/protocol.csp?' endpoint. The input is processed by the internal date '-s' command without rebooting or disrupting HTTP service. Unlike other injection points, this vector allows remote compromise without triggering visible configuration changes.

ingress-nginx admission controller RCE escalation

A security issue was discovered in Kubernetes where under certain conditions, an unauthenticated attacker with access to the pod network can achieve arbitrary code execution in the context of the ingress-nginx controller. This can lead to disclosure of Secrets accessible to the controller. (Note that in the default installation, the controller can access all Secrets cluster-wide.)

PostgreSQL quoting APIs miss neutralizing quoting syntax in text that fails encoding validation

Improper neutralization of quoting syntax in PostgreSQL libpq functions PQescapeLiteral(), PQescapeIdentifier(), PQescapeString(), and PQescapeStringConn() allows a database input provider to achieve SQL injection in certain usage patterns. Specifically, SQL injection requires the application to use the function result to construct input to psql, the PostgreSQL interactive terminal. Similarly, improper neutralization of quoting syntax in PostgreSQL command line utility programs allows a source of command line arguments to achieve SQL injection when client_encoding is BIG5 and server_encoding is one of EUC_TW or MULE_INTERNAL. Versions before PostgreSQL 17.3, 16.7, 15.11, 14.16, and 13.19 are affected.
