The otterdog webapp evaluates a format-string built from the incoming GitHub webhook JSON body using Python's eval(). When GITHUB_WEBHOOK_SECRET is unset or empty (default None), the HMAC signature check is skipped entirely, allowing an unauthenticated network client to reach the eval() sink with attacker-controlled input and execute arbitrary Python on the host.

A vulnerability was found in Chengdu Feiyuxing Technology VW2100 and VEC10GP version 1.0 B-MB3W202-210825-r11775, affecting the handle_wechat_cn_wifi function in var/html/webserver within the Weixin Auth Endpoint component. Manipulation of the extend argument results in OS command injection. The attack can be executed remotely and the exploit has been made public.

A weakness has been identified in Intelbras SG 2404 PoE L2+ versions 1.00.70 and 1.00.72, affecting an unknown function in the /EXCU_SHELL file within the Web Management Interface component. Manipulation can lead to improper authentication. The attack can be launched remotely and the exploit has been made publicly available.

Buffer overflow in the data receiving process in NEC WebSAM WinShare versions 7.5.0 and earlier, 7.6.0, and 7.7.0 through 7.7.2 on Windows allows a remote unauthenticated attacker to execute arbitrary code with SYSTEM privileges via a crafted packet with a malformed data size value in the protocol header.

Improper input validation in the network communication processing in NEC WebSAM WinShare versions 7.2.0 through 7.5.0, 7.6.0, and 7.7.0 through 7.7.2 on Windows allows a remote unauthenticated attacker to execute arbitrary commands with SYSTEM privileges via a crafted network packet sent to the computer running WinShare.

A vulnerability was found in D-Link DIR-878 version 1.20B05 in the GetCAPTCHAsetting function of bin/prog.cgi (HNAP Handler component). Manipulating the uid argument results in a heap-based buffer overflow. The attack can be initiated remotely and the exploit has been made public.

The Frontend Admin by DynamiApps plugin (acf-frontend-form-element) through version 3.30.1 contains an incorrect privilege assignment vulnerability. The flaw allows an attacker to escalate privileges within the WordPress site.

IBM Concert 1.0 through 3.0.1.1 allows an attacker to supply crafted input that is incorporated into an operating system command without adequate validation or sanitization. Successful exploitation allows remote attackers to execute arbitrary commands on the underlying operating system with the privileges of the affected service.

IBM Optim versions 1.0.0, 1.1.0, and 1.2.0 are vulnerable to path traversal, allowing a remote authenticated attacker to obtain sensitive information.
