Summary

Hide ▲

A new set of vulnerabilities, dubbed 2TETRA:2BURST, has been discovered in the Terrestrial Trunked Radio (TETRA) communications protocol, affecting its end-to-end encryption (E2EE) mechanism. These flaws allow for replay and brute-force attacks, potentially exposing encrypted traffic. The vulnerabilities were disclosed at the Black Hat USA security conference by researchers from Midnight Blue. The flaws impact TETRA networks used by law enforcement, military, transportation, utilities, and critical infrastructure operators. The vulnerabilities include issues with packet injection, insufficient fixes for previously disclosed flaws, and weaknesses in encryption algorithms. There is no evidence of these vulnerabilities being exploited in the wild, but patches are not yet available for most of the issues.

Akira Ransomware Exploits SonicWall SSL VPN Flaws and Misconfigurations

The Akira ransomware group has been actively exploiting vulnerabilities and misconfigurations in SonicWall SSL VPN devices to gain initial access to networks. This campaign has seen increased activity since late July 2025, targeting organizations globally, including those in Australia. The attacks leverage a year-old flaw (CVE-2024-40766) and misconfigured LDAP settings to bypass access controls and facilitate ransomware deployment. The threat actors use a combination of brute-forcing credentials, exploiting default configurations, and leveraging the Virtual Office Portal to configure multi-factor authentication (MFA) with valid accounts. These tactics allow them to bypass security measures and gain unauthorized access to networks. SonicWall has confirmed that recent SSLVPN activity is related to CVE-2024-40766, not a zero-day vulnerability. The affected firewall versions include specific models of Gen 5, Gen 6, and Gen 7 devices. Organizations are advised to update to firmware version 7.3.0 or later, rotate passwords, enforce MFA, mitigate the SSLVPN Default Groups risk, and restrict Virtual Office Portal access to trusted/internal networks to mitigate risks.

Critical SessionReaper vulnerability patched in Adobe Commerce and Magento Open Source

Adobe has patched a critical vulnerability (CVE-2025-54236) in its Commerce and Magento Open Source platforms, dubbed SessionReaper. This flaw, with a CVSS score of 9.1, could allow unauthenticated attackers to take control of customer accounts via the Commerce REST API. The patch was released on September 9, 2025, following an emergency notification to selected customers on September 4, 2025. Adobe Commerce on Cloud customers were already protected by a WAF rule deployed as an interim measure. The vulnerability is considered one of the most severe in the platform's history, with potential for widespread exploitation. Administrators are advised to apply the patch immediately, as it disables certain internal Magento functionalities that may affect custom or external code. The affected versions include Adobe Commerce 2.4.9-alpha2 and earlier, 2.4.8-p2 and earlier, 2.4.7-p7 and earlier, 2.4.6-p12 and earlier, 2.4.5-p14 and earlier, and 2.4.4-p15 and earlier. The affected versions also include Adobe Commerce B2B 1.5.3-alpha2 and earlier, 1.5.2-p2 and earlier, 1.4.2-p7 and earlier, 1.3.4-p14 and earlier, and 1.3.3-p15 and earlier. The affected versions include Magento Open Source 2.4.9-alpha2 and earlier, 2.4.8-p2 and earlier, 2.4.7-p7 and earlier, 2.4.6-p12 and earlier, and 2.4.5-p14 and earlier. The Custom Attributes Serializable module versions 0.1.0 to 0.4.0 are also affected.

Critical SAP NetWeaver Command Execution Vulnerabilities Patched

SAP has patched three critical vulnerabilities in NetWeaver, its middleware for business applications. The most severe flaw, CVE-2025-42944, allows unauthenticated attackers to execute arbitrary OS commands via insecure deserialization. Two other critical issues, CVE-2025-42922 and CVE-2025-42958, enable authenticated users to upload arbitrary files and unauthorized users to access administrative functions. These vulnerabilities affect SAP's ERP, CRM, SRM, and SCM applications, widely used in large enterprise networks. The patches come amid ongoing exploitation of another critical SAP vulnerability, CVE-2025-42957, which affects S/4HANA, Business One, and NetWeaver products. SAP released 21 new and four updated security notes on September 2025 patch day, including updates for NetWeaver AS ABAP and other SAP products. SAP has also released a patch for a high-severity missing input validation bug in SAP S/4HANA (CVE-2025-42916, CVSS score: 8.1).

Active exploitation of SAP S/4HANA command injection vulnerability CVE-2025-42957

A critical command injection vulnerability in SAP S/4HANA, tracked as CVE-2025-42957, is being actively exploited in the wild. The flaw allows attackers with low-privileged user access to execute arbitrary ABAP code, potentially leading to full system compromise. The vulnerability affects both on-premise and private cloud editions of SAP S/4HANA. The exploit can result in unauthorized modification of the SAP database, creation of superuser accounts, and theft of password hashes. Organizations are advised to apply patches immediately and monitor for suspicious activity. The vulnerability was fixed by the vendor on August 11, 2025, but several systems have not applied the available security updates, and these are now being targeted by hackers who have weaponized the bug. SecurityBridge discovered the vulnerability and reported it to SAP on June 27, 2025, and even assisted in the development of a patch. SecurityBridge and Pathlock have confirmed active exploitation of the vulnerability. The patch for CVE-2025-42957 is relatively easy to reverse engineer, and successful exploitation gives attackers access to the operating system and all data in the targeted SAP system. Organizations are urged to implement additional security measures, such as SAP's Unified Connectivity framework (UCON), to restrict RFC usage and monitor logs for suspicious activity.

Active exploitation of TP-Link TL-WA855RE Wi-Fi range extender vulnerability

The US Cybersecurity and Infrastructure Security Agency (CISA) has warned of active exploitation of a missing authentication vulnerability in TP-Link TL-WA855RE Wi-Fi range extender products. The flaw, tracked as CVE-2020-24363, allows attackers on the same network to send unauthenticated requests for a factory reset and reboot, potentially gaining administrative access. The vulnerability was disclosed in August 2020 and has been resolved by TP-Link in firmware updates. However, the product is now discontinued, and users are advised to discontinue its use. CISA has added the vulnerability to its Known Exploited Vulnerabilities (KEV) catalog, urging federal agencies to address it by September 23, 2025. On September 4, 2025, CISA added two additional TP-Link router vulnerabilities, CVE-2023-50224 and CVE-2025-9377, to its KEV catalog, noting evidence of active exploitation. These vulnerabilities affect multiple TP-Link router models, some of which have reached end-of-life status. TP-Link released firmware updates in November 2024 to address these issues, but recommends upgrading to newer hardware for enhanced protection.
