Это первая из трех частей, описывающих развитие процесса обучения инженеров АСУТП. Целью всех трех статей является попытка осмыслить подготовку инженеров АСУТП в ВУЗе (какая была, и какая есть сейчас), и обсудить с сообществом хабра, какой она должна быть в будущем. Каким образом ее можно актуализировать. Читать далее
Кодогенератор это программа, которая на основе исходного кода или какого-нибудь файла настроек генерирует вспомогательный код, который потом компилируется вместе с исходным кодом. Это нужно, чтобы не писать boilerplate-код, а также для получения дополнительных возможностей языка.Я…
security update
Fuji Electric Tellus Lite V-Simulator versions 4.0.12.0 and prior are vulnerable to a stack-based buffer overflow which may allow an attacker to execute arbitrary code.
OrangeScrum version 2.0.11 allows an authenticated external attacker to execute arbitrary commands on the server. This is possible because the application injects an attacker-controlled parameter into a system function.
Rapid7 Velociraptor allows users to be created with different privileges on the server. Administrators are generally allowed to run any command on the server including writing arbitrary files. However, lower privilege users are generally forbidden from writing or modifying files on the server. The VQL copy() function applies permission checks for reading files but does not check for permission to write files. This allows a low privilege user (usually, users with the Velociraptor "investigator"…
Rapid7 Velociraptor did not properly sanitize the client ID parameter to the CreateCollection API, allowing a directory traversal in where the collection task could be written. It was possible to provide a client id of "../clients/server" to schedule the collection for the server (as a server artifact), but only require privileges to schedule collections on the client. Normally, to schedule an artifact on the server, the COLLECT_SERVER permission is required. This permission is normally only…
A remote OScript execution issue was discovered in OpenText Content Suite Platform 22.1 (16.2.19.1803). Multiple endpoints allow the user to pass the parameter htmlFile, which is included in the HTML output rendering pipeline of a request. Because the Content Server evaluates and executes Oscript code in HTML files, it is possible for an attacker to execute Oscript code. The Oscript scripting language allows the attacker (for example) to manipulate files on the filesystem, create new network connections,…
An issue was discovered in OpenText Content Suite Platform 22.1 (16.2.19.1803). The request handler for ll.KeepAliveSession sets a valid AdminPwd cookie even when the Web Admin password was not entered. This allows access to endpoints, which require a valid AdminPwd cookie, without knowing the password.
An issue was discovered in OpenText Content Suite Platform 22.1 (16.2.19.1803). The Common Gateway Interface (CGI) program cs.exe allows an attacker to increase/decrease an arbitrary memory address by 1 and trigger a call to a method of a vftable with a vftable pointer value chosen by the attacker.
