A vulnerability classified as problematic was found in Unitech pm2 up to 6.0.6. This vulnerability affects unknown code of the file /lib/tools/Config.js. The manipulation leads to inefficient regular expression complexity. The attack can be initiated remotely. The exploit has been disclosed to the public and may be used.

A now-patched critical security flaw in the Wazur Server is being exploited by threat actors to drop two different Mirai botnet variants and use them to conduct distributed denial-of-service (DDoS) attacks. Akamai, which first discovered the exploitation efforts in late March 2025, said the malicious campaign targets CVE-2025-24016 (CVSS score: 9.9), an unsafe deserialization vulnerability that

The Authorino service in the Red Hat Connectivity Link is the authorization service for zero trust API security. Authorino allows the users with developer persona to add callbacks to be executed to HTTP endpoints once the authorization process is completed. It was found that an attacker with developer persona access can add a large number of those callbacks to be executed by Authorino and as the authentication policy is enforced by a single instance of the service, this leada to a Denial of Service in Authorino while processing the post-authorization callbacks.

### Summary A **Denial of Service (DoS)** vulnerability was discovered in the CoreDNS DNS-over-QUIC (DoQ) server implementation. The server previously created a new goroutine for every incoming QUIC stream without imposing any limits on the number of concurrent streams or goroutines. A remote, unauthenticated attacker could open a large number of streams, leading to uncontrolled memory consumption and eventually causing an Out Of Memory (OOM) crash — especially in containerized or memory-constrained environments. ### Impact - **Component**: `server_quic.go` - **Attack Vector**: Remote, network-based - **Attack Complexity**: Low - **Privileges Required**: None - **User Interaction**: None - **Impact**: High availability loss (OOM kill or unresponsiveness) This issue affects deployments with `quic://` enabled in the Corefile. A single attacker can cause the CoreDNS instance to become unresponsive using minimal bandwidth and CPU. ### Patches The patch introduces two key mitigation m...

### Summary There is a denial of service vulnerability in the Content-Disposition parsing component of Rack. This is very similar to the previous security issue CVE-2022-44571. ### Details Carefully crafted input can cause Content-Disposition header parsing in Rack to take an unexpected amount of time, possibly resulting in a denial of service attack vector. This header is used typically used in multipart parsing. Any applications that parse multipart posts using Rack (virtually all Rails applications) are impacted. ### Credits Thanks to [scyoon](https://hackerone.com/scyoon) for reporting this to the Rails security team

### Impact A vulnerability in Multer versions >=1.4.4-lts.1, <2.0.1 allows an attacker to trigger a Denial of Service (DoS) by sending an upload file request with an empty string field name. This request causes an unhandled exception, leading to a crash of the process. ### Patches Users should upgrade to `2.0.1` ### Workarounds None ### References https://github.com/expressjs/multer/commit/35a3272b611945155e046dd5cef11088587635e9 https://github.com/expressjs/multer/issues/1233 https://github.com/expressjs/multer/pull/1256

A buffer overflow vulnerability exists in the mstp.ko kernel module, responsible for processing BACnet MS/TP frames over serial (RS485). The SendFrame() function writes directly into a statically sized kernel buffer (alloc_entry(0x1f5)) without validating the length of attacker-controlled data (param_5). If an MS/TP frame contains a crafted payload exceeding 492 bytes, the function performs out-of-bounds writes beyond the allocated 501-byte buffer, corrupting kernel memory. This flaw allows local or physically connected attackers to trigger denial-of-service or achieve remote code execution in kernel space. Tested against version 3.08.03 with a custom BACnet frame over /dev/ttyS0.
