1Panel Unauthorized access in Backend

1Panel is an open source Linux server operation and maintenance management panel. In version 1.4.3, authenticated attackers can download arbitrary files through the API interface. This code has unauthorized access. Attackers can freely download the file content on the target system. This may cause a large amount of information leakage. Version 1.5.0 has a patch for this issue.

1Panel O&M management panel has a background arbitrary file reading vulnerability

1Panel is an open source Linux server operation and maintenance management panel. In version 1.4.3, arbitrary file reads allow an attacker to read arbitrary important configuration files on the server. In the `api/v1/file.go` file, there is a function called `LoadFromFile`, which directly reads the file by obtaining the requested path `parameter[path]`. The request parameters are not filtered, resulting in a background arbitrary file reading vulnerability. Version 1.5.0 has a patch for this issue.

Missing password confirmation when creating app passwords

Nextcloud Server provides data storage for Nextcloud, an open source cloud platform.

Nextcloud Talk Android version 17.0.0 has a patch for this issue. No known workarounds are available.

Electron: Out-of-package code execution when launched with arbitrary cwd

Electron is a framework which lets you write cross-platform desktop applications using JavaScript, HTML and CSS. Electron apps that are launched as command line executables are impacted. Specifically this issue can only be exploited if the following conditions are met: 1. The app is launched with an attacker-controlled working directory and 2. The attacker has the ability to write files to that working directory. This makes the risk quite low, in fact normally issues of this kind are considered outside of our threat model as similar to Chromium we exclude Physically Local Attacks but given the ability for this issue to bypass certain protections like ASAR Integrity it is being treated with higher importance. This issue has been fixed in versions:`26.0.0-beta.13`, `25.4.1`, `24.7.1`, `23.3.13`, and `22.3.19`. There are no app side workarounds, users must update to a patched version of Electron.

Notes attachment render HTML in preview mode

Notes is a note-taking app for Nextcloud, an open-source cloud platform. Starting in version 4.4.0 and prior to version 4.8.0, when creating a note file with HTML, the content is rendered in the preview instead of the file being offered to download. Nextcloud Notes app version 4.8.0 contains a patch for the issue. No known workarounds are available.

user_oidc app stores client secret unencrypted in database

user_oidc provides the OIDC connect user backend for Nextcloud, an open-source cloud platform. Starting in version 1.0.0 and prior to version 1.3.3, an attacker that obtained at least read access to a snapshot of the database can impersonate the Nextcloud server towards linked servers. user_oidc 1.3.3 contains a patch. No known workarounds are available.

Issuer not verified from obtained token in user_oidc

user_oidc provides the OIDC connect user backend for Nextcloud, an open-source cloud platform. Starting in version 1.0.0 and prior to version 1.3.3, missing verification of the issuer would have allowed an attacker to perform a man-in-the-middle attack returning corrupted or known token they also have access to. user_oidc 1.3.3 contains a patch. No known workarounds are available.

Advanced permissions not respected when copying entire group folders

Nextcloud Server provides data storage for Nextcloud, an open source cloud platform.

Instrumentation for AWS SDK v2 captures email content when using Amazon Simple Email Service (SES) v1 API, exposing that content to the telemetry backend

OpenTelemetry Java Instrumentation provides OpenTelemetry auto-instrumentation and instrumentation libraries for Java. OpenTelemetry Java Instrumentation prior to version 1.28.0 contains an issue related to the instrumentation of Java applications using the AWS SDK v2 with Amazon Simple Email Service (SES) v1 API. When SES POST requests are instrumented, the query parameters of the request are inserted into the trace `url.path` field. This behavior leads to the http body, containing the email subject and message, to be present in the trace request url metadata. Any user using a version before 1.28.0 of OpenTelemetry Java Instrumentation to instrument AWS SDK v2 call to SES’s v1 SendEmail API is affected. The e-mail content sent to SES may end up in telemetry backend. This exposes the e-mail content to unintended audiences. The issue can be mitigated by updating OpenTelemetry Java Instrumentation to version 1.28.0 or later.

Insufficient input validation in efibootguard

efibootguard is a simple UEFI boot loader with support for safely switching between current and updated partition sets. Insufficient or missing validation and sanitization of input from untrustworthy bootloader environment files can cause crashes and probably also code injections into `bg_setenv`) or programs using `libebgenv`. This is triggered when the affected components try to modify a manipulated environment, in particular its user variables. Furthermore, `bg_printenv` may crash over invalid read accesses or report invalid results. Not affected by this issue is EFI Boot Guard's bootloader EFI binary. EFI Boot Guard release v0.15 contains required patches to sanitize and validate the bootloader environment prior to processing it in userspace. Its library and tools should be updated, so should programs statically linked against it. An update of the bootloader EFI executable is not required. The only way to prevent the issue with an unpatched EFI Boot Guard version is to avoid accesses to user variables, specifically modifications to them.

OS command injection vulnerability in WRC-F1167ACF all versions, and WRC-1750GHBK all versions allows an attacker who can access the product to execute an arbitrary OS command by sending a specially crafted request.

Improper access control in some Intel(R) SUR software before version 2.4.10587 may allow an unauthenticated user to potentially enable denial of service via adjacent access.

SQL injection vulnerability in LuxCal Web Calendar prior to 5.2.3M (MySQL version) and LuxCal Web Calendar prior to 5.2.3L (SQLite version) allows a remote unauthenticated attacker to execute arbitrary queries against the database and obtain or alter the information in it.
