A critical vulnerability in Oracle E-Business Suite (EBS) allows unauthenticated attackers to access sensitive data via HTTP. The flaw, CVE-2025-61884, affects versions 12.2.3 through 12.2.14 and has a CVSS score of 7.5. CISA has confirmed that the vulnerability is being exploited in attacks and has added it to its Known Exploited Vulnerabilities catalog. Oracle has issued an emergency security update and patch, but exploitation in the wild has been reported. The vulnerability is in the Runtime UI component and could lead to unauthorized access to critical data. Oracle has silently fixed the vulnerability after it was actively exploited and a proof-of-concept exploit was leaked by the ShinyHunters extortion group. This development follows recent disclosures of zero-day exploitation in EBS software, attributed to a group with ties to the Clop ransomware group. The Clop group has been involved in major data theft campaigns targeting zero-days in Accellion FTA, GoAnywhere MFT, Cleo, and MOVEit Transfer.

Active exploitation of critical vulnerabilities in Gladinet's CentreStack and Triofox products continues. The zero-day vulnerability, CVE-2025-11371, is an unauthenticated local file inclusion bug that allows unintended disclosure of system files. This flaw affects all versions prior to and including 16.7.10368.56560. The vulnerability has been exploited to retrieve the machine key from the application Web.config file, enabling remote code execution via a ViewState deserialization vulnerability. Three customers have been impacted so far. A patch for the zero-day vulnerability CVE-2025-11371 is now available in CentreStack version 16.10.10408.56683. Users are advised to upgrade to this version or, if upgrading is not possible, disable the "temp" handler within the Web.config file for UploadDownloadProxy to mitigate the risk. The vendor, Gladinet, has been notified and is working on a fix. The vulnerability was detected by researchers at Huntress on September 27, 2025. The flaw was exploited to obtain a machine key and execute code remotely. The attack used an older deserialization vulnerability (CVE-2025-30406) to achieve remote code execution (RCE) through ViewState. The mitigations will impact some functionality of the platform but prevent exploitation of CVE-2025-11371. The U.S. Cybersecurity and Infrastructure Security Agency (CISA) added CVE-2025-11371 to its Known Exploited Vulnerabilities (KEV) catalog on November 5, 2025, citing evidence of active exploitation. Federal Civilian Executive Branch (FCEB) agencies are required to apply the necessary fixes by November 25, 2025, to secure their networks. Additionally, a new critical vulnerability, CVE-2025-12480 (CVSS score: 9.8), has been discovered in Gladinet's Triofox file-sharing and remote access platform. This flaw allows attackers to bypass authentication and access configuration pages, resulting in the upload and execution of arbitrary payloads. The threat cluster tracked as UNC6485 has been exploiting this flaw since August 24, 2025. The attackers have used the built-in antivirus feature to execute malicious files and set up encrypted tunnels to command-and-control servers, leveraging remote access tools like Zoho Assist and AnyDesk for further exploitation. The vulnerability CVE-2025-12480 was discovered and reported by Mandiant on November 10. The flaw allows an attacker to gain access to initial setup pages even after setup is complete, enabling the upload and execution of arbitrary payloads. The exploitation campaign started on August 14, 2025. The attackers exploited an HTTP Host header vulnerability by spoofing localhost in requests, bypassing access controls to reach the normally restricted AdminDatabase.aspx setup page. The flaw stemmed from missing origin validation and over-reliance on the host header, allowing unauthenticated remote access to critical configuration pages. The attackers logged in using the newly created Admin account and uploaded malicious files to execute them using the built-in anti-virus feature. A new actively exploited vulnerability in Gladinet's CentreStack and Triofox products has been disclosed, stemming from the use of hard-coded cryptographic keys. This flaw affects nine organizations so far. The use of hard-coded cryptographic keys could allow threat actors to decrypt or forge access tickets, enabling them to access sensitive files like web.config that can be exploited to achieve ViewState deserialization and remote code execution. The attacks involve specially crafted URL requests to the "/storage/filesvr.dn" endpoint, with the Username and Password fields left blank, causing the application to fall back to the IIS Application Pool Identity. The timestamp field in the access ticket is set to 9999, creating a ticket that never expires, allowing threat actors to reuse the URL indefinitely to download the server configuration. Organizations using CentreStack and Triofox are advised to update to the latest version, 16.12.10420.56791, released on December 8, 2025, and scan logs for the presence of the string "vghpI7EToZUDIZDdprSubL3mTZ2," which is the encrypted representation of the web.config file path. In the event of indicators of compromise (IoCs), it is imperative to rotate the machine key by generating new keys in the IIS Manager and restarting IIS after repeating the same step for all worker nodes.

A critical security flaw in the Sudo command-line utility for Linux and Unix-like operating systems, identified as CVE-2025-32463, is being actively exploited. This vulnerability affects Sudo versions 1.9.14 through 1.9.17 and allows local attackers to run arbitrary commands as root, even if they are not listed in the sudoers file. The flaw was disclosed in July 2025 and added to CISA's Known Exploited Vulnerabilities (KEV) catalog on September 30, 2025. The U.S. Cybersecurity and Infrastructure Security Agency (CISA) has advised Federal Civilian Executive Branch (FCEB) agencies to apply necessary mitigations by October 20, 2025, to secure their networks. The vulnerability was disclosed by Stratascale researcher Rich Mirch in July 2025. The flaw affects sudo versions 1.9.14 through 1.9.17 and has received a critical severity score of 9.3 out of 10. A proof-of-concept exploit for the CVE-2025-32463 flaw was released on July 4, 2025, and additional exploits have circulated publicly since July 1, 2025.

A critical deserialization vulnerability (CVE-2025-5086) in Dassault Systèmes DELMIA Apriso Manufacturing Operations Management (MOM) software is actively exploited, with a CVSS score of 9.0. The flaw affects versions from Release 2020 through Release 2025 and allows for remote code execution (RCE). In addition to CVE-2025-5086, two more vulnerabilities (CVE-2025-6205 and CVE-2025-6204) in DELMIA Apriso have been identified and are actively exploited. CVE-2025-6205 is a critical-severity missing authorization flaw, and CVE-2025-6204 is a high-severity code injection vulnerability. Both were patched by Dassault Systèmes in early August 2025. The vulnerabilities can be chained together to create accounts with elevated privileges and place executable files into a web-served directory. The product exposes a SOAP-based message processor endpoint that accepts XML payloads for bulk employee/identity provisioning and a file upload API used by portal components but that is accessible only post-authentication. DELMIA Apriso is used in production processes for digitalizing and monitoring, and is deployed in automotive, aerospace, electronics, high-tech, and industrial machinery divisions. CISA has added these flaws to its Known Exploited Vulnerabilities (KEV) catalog, and FCEB agencies are advised to apply updates by November 18, 2025, to secure their networks. Additionally, a new vulnerability (CVE-2025-24893) in XWiki has been identified and is actively exploited. This flaw allows for arbitrary remote code execution through a request to the /bin/get/Main/SolrSearch endpoint and is being exploited in a two-stage attack chain that delivers a cryptocurrency miner. The vulnerability was reported by John Kwak of Trend Micro in May 2024 and was addressed in XWiki versions 15.10.11, 16.4.1, and 16.5.0RC1 in June 2024. Technical details on the bug emerged roughly half a year later, and an NVD advisory was published in February 2025. Numerous proof-of-concept (PoC) exploits targeting the vulnerability have been available since early 2025. CrowdSec observed the vulnerability being abused for reconnaissance earlier this year but noted a decline in activity. VulnCheck identified in-the-wild attacks exploiting CVE-2025-24893 to deploy a cryptocurrency miner. The attacks proceed in a two-pass workflow separated by at least 20 minutes: the first pass stages a downloader, and the second pass executes it. The observed traffic originates from an IP address geolocated to Vietnam that has been associated with other malicious activity. The RondoDox botnet has been observed targeting unpatched XWiki instances to exploit CVE-2025-24893. VulnCheck observed a spike in exploitation attempts, with peaks on November 7 and November 11, 2025. RondoDox is adding new exploitation vectors to rope susceptible devices into a botnet for conducting DDoS attacks using HTTP, UDP, and TCP protocols. The first RondoDox exploit was observed on November 3, 2025. Other attacks have been observed exploiting the flaw to deliver cryptocurrency miners, establish a reverse shell, and conduct general probing activity using a Nuclei template for CVE-2025-24893.
