Всем привет, меня зовут Евгений Гончаров, кто меня не знает, узнает позже, пост посвящается знающим меня людям.
За последние дни кибер-конференций меня спрашивали "как ты это делаешь, откуда энергия", вопросов было много, на которые я отвечал "у меня есть своя система знаний”.
Система видения мира созданная собственным сознанием, системно организованная, где все практики, результаты, теория - взяты из сугубо личного опыта подтвержденного годами жизни.
Некоторым я рассказываю "как и что", некоторым говорю основы или указываю на ошибки, но действительно - мне хочется отрефлексировать этот опыт в слух, без телефонов, гаджетов.
Мы можем настроиться. Дайте мне знать через форму о своей готовности к участию.
Кто готов. Давайте попробуем в какой-нибудь день вместе послушать о моем “точечном мире”.

/ Fileless Remote Code Execution on Juniper Firewalls
In this blog, was demonstrated how CVE-2023-36845, a vulnerability flagged as “Medium” severity by Juniper, can be used to remotely execute arbitrary code without authentication. Authors turned a multi-step (but very good) exploit into an exploit that can be written using a single curl command and appears to affect more (older) systems..:

/ GitLab Critical Security Release: 16.3.4 and 16.2.7
These versions contain important security fixes, and GitLab strongly recommend that all GitLab installations be upgraded to one of these versions immediately.
In short: A stored XSS vulnerability was discovered in GitLab.com that allowed an attacker to inject HTML in any note, issue denoscription, or wiki page by abusing syntax_highlight_filter.rb. The vulnerability was caused by the lack of proper input sanitization. The attacker could inject a noscript tag by using the base tag and loading the noscript from their own domain, bypassing the CSP. This could lead to the creation of tokens and take over of SSO accounts.
