В этой статье я расскажу вам о том, как ровно год назад я связал в цепочку несколько проблем безопасности для достижения Удаленного выполнения кода (RCE) на нескольких серверах компании VK. Я постарался описать свои шаги в подробностях, так как мне самому, как постоянному читателю отчетов по баг-баунти, всегда хочется понять, как исследователь мыслит во время обнаружения необычных уязвимостей. Надеюсь, для вас эта статья будет интересна. Читать далее
A vulnerability in the web interface of Cisco Prime Infrastructure could allow an unauthenticated, remote attacker to redirect a user to a malicious web page, aka an Open Redirect. The vulnerability is due to improper input validation of the parameters in the HTTP request. An attacker could exploit this vulnerability by crafting an HTTP request that could cause the web application to redirect the request to a specific malicious URL. This vulnerability is known as an open redirect attack and is used in…
Next.js versions >=9.5.0 and <9.5.4 are vulnerable to an Open Redirect. Specially encoded paths could be used with the trailing slash redirect to allow an open redirect to occur to an external site. In general, this redirect does not directly harm users although can allow for phishing attacks by redirecting to an attackers domain from a trusted domain. The issue is fixed in version 9.5.4.
Open Forms is an application for creating and publishing smart forms. Prior to versions 1.0.9 and 1.1.1, the cookie consent page in Open Forms contains an open redirect by injecting a `referer` querystring parameter and failing to validate the value. A malicious actor is able to redirect users to a website under their control, opening them up for phishing attacks. The redirect is initiated by the open forms backend which is a legimate page, making it less obvious to end users they are being redirected to a
