### Summary The Butterfly framework uses the `java.net.URL` class to refer to (what are expected to be) local resource files, like images or templates. This works: "opening a connection" to these URLs opens the local file. However, if a `file:/` URL is directly given where a relative path (resource name) is expected, this is also accepted in some code paths; the app then fetches the file, from a remote machine if indicated, and uses it as if it was a trusted part of the app's codebase. This leads to multiple weaknesses and potential weaknesses: * An attacker that has network access to the application could use it to gain access to files, either on the the server's filesystem (path traversal) or shared by nearby machines (server-side request forgery with e.g. SMB). * An attacker that can lead or redirect a user to a crafted URL belonging to the app could cause arbitrary attacker-controlled JavaScript to be loaded in the victim's browser (cross-site scripting). * If an app is written ...

### Summary In the `database` extension, the "enable_load_extension" property can be set for the SQLite integration, enabling an attacker to load (local or remote) extension DLLs and so run arbitrary code on the server. The attacker needs to have network access to the OpenRefine instance. ### Details The `database` extension, with some restrictions, lets users connect to any database they wish by filling in different parts of the JDBC URL that is used. For the SQLite integration, the extension expects a file path pointing to a database file (or a place where such a file can be created). This means that users can: * Read files on local or SMB filesystems, provided they are SQLite databases. * Write to files on local or SMB filesystems, as long as those files are either SQLite databases or empty. This seems to be the expected behavior. However, by adding `?enable_load_extension=true` to the filename, a [feature](https://www.sqlite.org/loadext.html) is toggled that additionally all...

Cybersecurity researchers have discovered an advanced version of the Qilin ransomware sporting increased sophistication and tactics to evade detection. The new variant is being tracked by cybersecurity firm Halcyon under the moniker Qilin.B. "Notably, Qilin.B now supports AES-256-CTR encryption for systems with AESNI capabilities, while still retaining Chacha20 for systems that lack this support

Credential theft was the main goal in 25% of incidents last quarter, and new ransomware variants made their appearance - read more about the top trends, TTPs, and security weaknesses that facilitated adversary actions.

The Russian-language malware primarily enlists computers to mine Monero, but theoretically it can do worse.

New variants of a banking malware called Grandoreiro have been found to adopt new tactics in an effort to bypass anti-fraud measures, indicating that the malicious software is continuing to be actively developed despite law enforcement efforts to crack down on the operation. "Only part of this gang was arrested: the remaining operators behind Grandoreiro continue attacking users all over the

WarmCookie is a malware family that emerged in April 2024 and has been distributed via regularly conducted malspam and malvertising campaigns.

TA866 (also known as Asylum Ambuscade) is a threat actor that has been conducting intrusion operations since at least 2020.

Threat actors have been observed abusing Amazon S3 (Simple Storage Service) Transfer Acceleration feature as part of ransomware attacks designed to exfiltrate victim data and upload them to S3 buckets under their control. "Attempts were made to disguise the Golang ransomware as the notorious LockBit ransomware," Trend Micro researchers Jaromir Horejsi and Nitesh Surana said. "However, such is
