The maintainers of the FreeBSD Project have released security updates to address a high-severity flaw in OpenSSH that attackers could potentially exploit to execute arbitrary code remotely with elevated privileges. The vulnerability, tracked as CVE-2024-7589, carries a CVSS score of 7.4 out of a maximum of 10.0, indicating high severity. "A signal handler in sshd(8) may call a logging function

A list of topics we covered in the week of August 5 to August 11 of 2024

Security vulnerabilities have been disclosed in the industrial remote access solution Ewon Cosy+ that could be abused to gain root privileges to the devices and stage follow-on attacks. The elevated access could then be weaponized to decrypt encrypted firmware files and encrypted data such as passwords in configuration files, and even get correctly signed X.509 VPN certificates for foreign

As many as 10 security flaws have been uncovered in Google's Quick Share data transfer utility for Android and Windows that could be assembled to trigger remote code execution (RCE) chain on systems that have the software installed. "The Quick Share application implements its own specific application-layer communication protocol to support file transfers between nearby, compatible devices,"

Cybersecurity researchers have discovered multiple critical flaws in Amazon Web Services (AWS) offerings that, if successfully exploited, could result in serious consequences. "The impact of these vulnerabilities range between remote code execution (RCE), full-service user takeover (which might provide powerful administrative access), manipulation of AI modules, exposing sensitive data, data

CometVisu's file system endpoints don't require authentication and additionally the endpoint to update an existing file is susceptible to path traversal. This makes it possible for an attacker to overwrite existing files on the openHAB instance. If the overwritten file is a shell script that is executed at a later time this vulnerability can allow remote code execution by an attacker. This vulnerability was discovered with the help of CodeQL's [Uncontrolled data used in path expression](https://codeql.github.com/codeql-query-help/java/java-path-injection/) query. ## Impact This issue may lead up to Remote Code Execution (RCE).

The [proxy endpoint](https://github.com/openhab/openhab-webui/blob/1c03c60f84388b9d7da0231df2d4ebb1e17d3fcf/bundles/org.openhab.ui.cometvisu/src/main/java/org/openhab/ui/cometvisu/internal/backend/rest/ProxyResource.java#L83) of openHAB's CometVisu add-on can be accessed without authentication. This proxy-feature can be exploited as Server-Side Request Forgery (SSRF) to induce GET HTTP requests to internal-only servers, in case openHAB is exposed in a non-private network. Furthermore, this proxy-feature can also be exploited as a Cross-Site Scripting (XSS) vulnerability, as an attacker is able to re-route a request to their server and return a page with malicious JavaScript code. Since the browser receives this data directly from the openHAB CometVisu UI, this JavaScript code will be executed with the origin of the CometVisu UI. This allows an attacker to exploit call endpoints on an openHAB server even if the openHAB server is located in a private network. (e.g. by sending an openHAB...

Microsoft on Thursday disclosed four medium-severity security flaws in the open-source OpenVPN software that could be chained to achieve remote code execution (RCE) and local privilege escalation (LPE). "This attack chain could enable attackers to gain full control over targeted endpoints, potentially resulting in data breaches, system compromise, and unauthorized access to sensitive information

Cybersecurity researchers have uncovered weaknesses in Sonos smart speakers that could be exploited by malicious actors to clandestinely eavesdrop on users. The vulnerabilities "led to an entire break in the security of Sonos's secure boot process across a wide range of devices and remotely being able to compromise several devices over the air," NCC Group security researchers Alex Plaskett and

At Black Hat USA, security researcher Michael Bargury released a "LOLCopilot" ethical hacking module to demonstrate how attackers can exploit Microsoft Copilot — and offered advice for defensive tooling.
