Cacheservice did not correctly check if relative cache object were pointing to the defined absolute location when accessing resources. An attacker with access to the database and a local or restricted network would be able to read arbitrary local file system resources that are accessible by the services system user account. We have improved path validation and make sure that any access is contained to the defined root directory. No publicly available exploits are known.
In case Cacheservice was configured to use a sproxyd object-storage backend, it would follow HTTP redirects issued by that backend. An attacker with access to a local or restricted network with the capability to intercept and replay HTTP requests to sproxyd (or who is in control of the sproxyd service) could perform a server-side request-forgery attack and make Cacheservice connect to unexpected resources. We have disabled the ability to follow HTTP redirects when connecting to sproxyd resources. No…
Full-text autocomplete search allows user-provided SQL syntax to be injected to SQL statements. With existing sanitization in place, this can be abused to trigger benign SQL Exceptions but could potentially be escalated to a malicious SQL injection vulnerability. We now properly encode single quotes for SQL FULLTEXT queries. No publicly available exploits are known.
Frontend themes are defined by user-controllable jslob settings and could point to a malicious resource which gets processed during login. Malicious script code can be executed within the victims context. This can lead to session hijacking or triggering unwanted actions via the web interface and API. To exploit this an attacker would require temporary access to the users account or lure a user to a compromised account. We now sanitize the theme value and use a default fallback if no theme matches. No…
The users clientID at "application passwords" was not sanitized or escaped before being added to DOM. Malicious script code can be executed within the victims context. This can lead to session hijacking or triggering unwanted actions via the web interface and API. To exploit this an attacker would require temporary access to the users account or lure a user to a compromised account. We now sanitize the user-controllable clientID parameter. No publicly available exploits are known.
The "upsell" widget for the portal allows to specify a product description. This description taken from a user-controllable jslob did not get escaped before being added to DOM. Malicious script code can be executed within the victims context. This can lead to session hijacking or triggering unwanted actions via the web interface and API. To exploit this an attacker would require temporary access to the users account or lure a user to a compromised account. We now sanitize jslob content. No…
Custom log-in and log-out locations are used-defined as jslob but were not checked to contain malicious protocol handlers. Malicious script code can be executed within the victims context. This can lead to session hijacking or triggering unwanted actions via the web interface and API. To exploit this an attacker would require temporary access to the users account or lure a user to a compromised account. We now sanitize jslob content for those locations to avoid redirects to malicious content. No publicly…

Наверно, у всех есть этот друг или знакомый, глядя на которого, ломает от несправедливости. Он никогда не задумывается о том, что съесть. Ест много, вкусно и пока все стараются скинуть пару кг, этот ведьмак/ведьма мечтает набрать вес и у него это плохо получается. Да и вообще не друг
«Пять глаз», «Девять глаз» и «Четырнадцать глаз» — это реально существующие международные альянсы по массовому наблюдению, включающие в себя, соответственно, 5, 9 и 14 западных стран, а также партнёрские страны-сателлиты. На основе соглашений в основе этих альянсов, спецслужбы…
