Cybersecurity researchers have disclosed a high-severity security flaw in the PostgreSQL open-source database system that could allow unprivileged users to alter environment variables, and potentially lead to code execution or information disclosure. The vulnerability, tracked as CVE-2024-10979 , carries a CVSS score of 8.8. Environment variables are user-defined values that can allow a program to dynamically fetch various kinds of information, such as access keys and software installation paths, during runtime without having to hard-code them. In certain operating systems, they are initialized during the startup phase. "Incorrect control of environment variables in PostgreSQL PL/Perl allows an unprivileged database user to change sensitive process environment variables (e.g., PATH )," PostgreSQL said in an advisory released Thursday. "That often suffices to enable arbitrary code execution, even if the attacker lacks a database server operating system user." ...

Security researchers have disclosed almost a dozen security flaws impacting the GE HealthCare Vivid Ultrasound product family that could be exploited by malicious actors to tamper with patient data and even install ransomware under certain circumstances. "The impacts enabled by these flaws are manifold: from the implant of ransomware on the ultrasound machine to the access and manipulation of patient data stored on the vulnerable devices," operational technology (OT) security vendor Nozomi Networks  said  in a technical report. The security issues impact the Vivid T9 ultrasound system and its pre-installed Common Service Desktop web application, which is exposed on the localhost interface of the device and allows users to perform administrative actions. They also affect another software program called EchoPAC that's installed on a doctor's Windows workstation to help them access multi-dimensional echo, vascular, and abdominal ultrasound images. That being said, s...

CrowdStrike is named a Leader in the 2024 Gartner® Magic Quadrant™ for Endpoint Protection Platforms for the fifth consecutive time, positioned highest on Ability to Execute and furthest to the right on Completeness of Vision.

Several popular Android applications available in Google Play Store are susceptible to a path traversal-affiliated vulnerability codenamed the Dirty Stream attack that could be exploited by a malicious app to overwrite arbitrary files in the vulnerable app's home directory. "The implications of this vulnerability pattern include arbitrary code execution and token theft, depending on an application's implementation," Dimitrios Valsamaras of the Microsoft Threat Intelligence team  said  in a report published Wednesday. Successful exploitation could allow an attacker to take full control of the application's behavior and leverage the stolen tokens to gain unauthorized access to the victim's online accounts and other data. Two of the apps that were found vulnerable to the problem are as follows - Xiaomi File Manager (com.mi. Android.globalFileexplorer) - Over 1 billion installs WPS Office (cn.wps.m...

A security vulnerability has been discovered in the R programming language that could be exploited by a threat actor to create a malicious RDS (R Data Serialization) file such that it results in code execution when loaded and referenced. The flaw, assigned the CVE identifier CVE-2024-27322 (CVSS score: 8.8), "involves the use of promise objects and lazy evaluation in R," AI application security company HiddenLayer said in a report shared with The Hacker News. RDS,  like pickle in Python , is a format used to serialize and save the state of data structures or objects in R, an open-source programming language used in statistical computing, data visualization, and machine learning. This process of serialization – serialize() or saveRDS() – and deserialization – unserialize() and readRDS() – is also leveraged when saving and loading R packages. The root cause behind CVE-2024-27322 lies in the fact that it could lead to arbitrary code execution when deseriali...

WordPress has released version 6.4.2 with a patch for a critical security flaw that could be exploited by threat actors by combining it with another bug to execute arbitrary PHP code on vulnerable sites. "A remote code execution vulnerability that is not directly exploitable in core; however, the security team feels that there is a potential for high severity when combined with some plugins, especially in multisite installations," WordPress  said . According to WordPress security company Wordfence, the  issue  is rooted in the WP_HTML_Token class that was introduced in version 6.4 to improve HTML parsing in the block editor. A threat actor with the ability to exploit a PHP object injection vulnerability present in any other plugin or theme to chain the two issues to execute arbitrary code and seize control of the targeted site. "If a  POP [property-oriented programming] chain  is present via an additional plugin or theme installed on the target system, it ...

The maintainers of Python Package Index (PyPI) last week issued fixes for three vulnerabilities, one among which could be abused to achieve arbitrary code execution and take full control of the official third-party software repository. The security weaknesses were  discovered  and reported by Japanese security researcher RyotaK, who in the past has disclosed critical vulnerabilities in the  Homebrew Cask repository  and Cloudflare's  CDNJS library . He was awarded a total of $3,000 as part of the bug bounty program. The list of three vulnerabilities is as follows - Vulnerability in Legacy Document Deletion on PyPI  - An exploitable vulnerability in the mechanisms for deleting legacy documentation hosting deployment tooling on PyPI, which would allow an attacker to remove documentation for projects not under their control. Vulnerability in Role Deletion on PyPI  - An exploitable vulnerability in the mechanisms for deleting roles on PyPI was disco...

Cybersecurity researchers have disclosed new security vulnerabilities in the Etherpad text editor (version 1.8.13) that could potentially enable attackers to hijack administrator accounts, execute system commands, and even steal sensitive documents. The two flaws — tracked as CVE-2021-34816 and CVE-2021-34817 — were discovered and reported on June 4 by researchers from SonarSource, following which patches have been shipped for the latter in  version 1.8.14  of Etherpad released on July 4. Etherpad is a real-time collaborative interface that enables a document to be edited simultaneously by multiple authors. It is an open-source alternative to Google Docs that can be self-hosted or used through one of the many third-party public instances available. "The XSS vulnerability allows attackers to take over Etherpad users, including admins. This can be used to steal or manipulate sensitive data," SonarSource vulnerability researcher Paul Gerste  said  in a report shar...
