It was possible to call filesystem and network references using the local LibreOffice instance using manipulated ODT documents. Attackers could discover restricted network topology and services as well as including local files with read permissions of the open-xchange system user. This was limited to specific file-types, like images. We have improved existing content filters and validators to avoid including any local resources. No publicly available exploits are known.
Attackers with access to the "documentconverterws" API were able to inject serialized Java objects, that were not properly checked during deserialization. Access to this API endpoint is restricted to local networks by default. Arbitrary code could be injected that is being executed when processing the request. A check has been introduced to restrict processing of legal and expected classes for this API. We now log a warning in case there are attempts to inject illegal classes. No publicly…
Системы рекуперации и теплоутилизации - это реальная экономия денег при эксплуатации систем вентиляции или просто распил бюджета на дополнительное оборудование?В нескольких предыдущих статьях было достаточно подробно разобрано положение дел с вентиляцией и…
Default permissions for a properties file were too permissive. Local system users could read potentially sensitive information. We updated the default permissions for noreply.properties set during package installation. No publicly available exploits are known.
Attackers can successfully request arbitrary snippet IDs, including E-Mail signatures of other users within the same context. Signatures of other users could be read even though they are not explicitly shared. We improved permission handling when requesting snippets that are not explicitly shared with other users. No publicly available exploits are known.
Control characters were not removed when exporting user feedback content. This allowed attackers to include unexpected content via user feedback and potentially break the exported data structure. We now drop all control characters that are not whitespace character during the export. No publicly available exploits are known.
IPv4-mapped IPv6 addresses did not get recognized as "local" by the code and a connection attempt is made. Attackers with access to user accounts could use this to bypass existing deny-list functionality and trigger requests to restricted network infrastructure to gain insight about topology and running services. We now respect possible IPV4-mapped IPv6 addresses when checking if contained in a deny-list. No publicly available exploits are known.
Чугун мы делаем в доменной печи. Сверху засыпаем руду и кокс в качестве топлива, снизу задуваем воздух, который обеспечивает горение. В результате получаем чугун и доменный газ. Доменный газ можно сжечь где-то ещё и получить энергию. Собственно, мы так и делаем, только смешиваем…
Cloudflare WARP client for Windows (up to v2023.3.381.0) allowed a malicious actor to remotely access the warp-svc.exe binary due to an insufficient access control policy on an IPC Named Pipe. This would have enabled an attacker to trigger WARP connect and disconnect commands, as well as obtaining network diagnostics and application configuration from the target's device. It is important to note that in order to exploit this, a set of requirements would need to be met, such as the target's…
Всем привет! Я Олег Королев, директор по аналитике в компании AGIMA. Нам часто прилетают задачи, связанные с разметкой сайтов. Заказчики хотят знать, как пользователи ведут себя в их веб-приложениях: что читают, что пролистывают, где застревают надолго и т. д. Эти сведения помогают…
