Improper neutralization of special elements used in an OS command in certain ASUS Router firmware allows an unauthenticated nearby user to trigger a chain of actions—unauthenticated queries, identifier guessing, credential overwriting, and command injection—resulting in the execution of arbitrary commands with root privileges. Refer to the ' Security Update for ASUS Router Firmware ' section on the ASUS Security Advisory for more information.

FastNetMon is a high-performance DDoS detector and sensor. In version 1.2.9 and earlier, the NetFlow v9 collector calls  strlen()  on an attacker-controlled interface-description field without bounding the scan to the field’s declared length. Although fields longer than 128 bytes are excluded from this operation, an accepted field without a null terminator can cause reads beyond the field and packet buffer. An unauthenticated remote attacker who can send crafted UDP packets to the collector can trigger an out-of-bounds read and potentially crash the process, causing denial of service. No fixed release is available as of this review.

ntopng is a web-based network traffic monitoring application.

ModSecurity is an open source, cross platform web application firewall (WAF) engine for Apache, IIS and Nginx. From 3.0.15 until 3.0.17, XML request body processing with SecParseXmlIntoArgs set to On or OnlyArgs can leave XMLNodes::parsing_ctx_arg uninitialized in the SAX end-element callback. A single crafted unauthenticated HTTP request can make a worker dereference the pointer, resulting in a constant-value write to an attacker-controlled address. The resulting memory corruption can terminate the worker and may disclose memory or redirect execution. Earlier 3.0.x releases and ModSecurity 2.x do not use the affected path. This issue is fixed in version 3.0.17.

FastNetMon is a high-performance DDoS detector and sensor. In version 1.2.9 and earlier, peer_find_template() in src/netflow_plugin/netflow_collector.cpp and src/netflow_plugin/netflow_v9_collector.cpp returns a pointer into global_netflow9_templates after releasing the cache mutex. On deployments with at least two entries in netflow_ports, concurrent template redefinition and data-flowset processing can let add_update_peer_template() reassign the template and free its records vector while another listener dereferences the escaped pointer. An unauthenticated sender that can reach both NetFlow/IPFIX listener ports can trigger a heap-use-after-free and reliably crash FastNetMon. No fixed release is available as of this review.

Novu provides an API for sending notifications through multiple channels. Prior to 3.17.0, validateUrlSsrf in libs/application-generic/src/utils/ssrf-url-validation.ts uses the isPrivateIp deny-list without covering the RFC6598 100.64.0.0/10 shared address space or its IPv4-mapped IPv6 forms. The workflow HTTP request step and webhook filter condition can therefore send server-side requests when a configured literal address or resolved hostname falls in that range. In Alibaba Cloud, 100.100.100.200 may expose instance metadata, while self-hosted and multi-tenant deployments may expose provider-internal services, private infrastructure, service meshes, or VPN resources reachable through CGNAT addressing. This issue is fixed in version 3.17.0.

Rack is a modular Ruby web server interface. Prior to 2.2.25, 3.1.23, and 3.2.8, Rack::Multipart::Parser.parse_boundary can skip a leading empty or quoted boundary parameter in a multipart Content-Type header and accept a later parameter. Rack can therefore parse a request body with a boundary that a conforming intermediary would not derive, allowing form fields or file uploads to reach an application without the intended proxy or web application firewall inspection. This issue is fixed in versions 2.2.25, 3.1.23, and 3.2.8.

ModSecurity is an open source, cross platform web application firewall (WAF) engine for Apache, IIS and Nginx. Prior to 2.9.15 and 3.0.17, msre_fn_removeComments_execute in apache2/re_tfns.c and inplace() in src/actions/transformations/remove_comments.cc implement t:removeComments by copying the character immediately after a comment terminator without re-evaluating it. Adjacent comments can therefore leave a later comment in the transformed value, allowing inline-comment obfuscation to bypass rules that depend on comment stripping. When a comment terminator is the final content, the same copy reads one byte beyond the input buffer. This issue is fixed in versions 2.9.15 and 3.0.17.

Versa has confirmed a buffer overflow vulnerability in the IPsec implementation on VOS, aka Versa FlexVNF.  Buffer Overflow Vulnerability Description When a maliciously crafted IKE Auth packet is sent to VOS, the vsmd process crashes, thereby resulting in a Denial of Service. An attacker can create a Denial-of-Service attack on the VOS appliances by crafting a malicious IKE Auth packet and sending it to the WAN interfaces on the VOS. During the IKE Authentication phase, if the IKE SA negotiation fails, and the size of the Remote ID is larger than the buffer size used to process the Remote ID, it will result in a crash of the vsmd process on the VOS appliance. What is impacted? VOS nodes configured with IPsec VPN profiles of type controller-staging-sdwan or remote-access-server using a WAN interface as the IPsec endpoint are vulnerable. (IPsec profiles configured with an overlay interface as the IPsec endpoint are not affected.) This configuration typically applies to all Controllers, Hub Controllers, and SSE Gateways. Additionally, site-to-site VPN profiles configured without a peer IP address, hostname, or FQDN are also vulnerable. What is not impacted? The VOS nodes listed above are not vulnerable if they are not accessible from the Internet.

ModSecurity is an open source, cross platform web application firewall (WAF) engine for Apache, IIS and Nginx. Prior to 2.9.15 and 3.0.17, the HttpsClient::download function in src/utils/https_client.cc sets libcurl CURLOPT_SSL_VERIFYHOST to 1 instead of the strict value 2L. Under adversary-in-the-middle and TLS interception conditions, this non-strict setting may weaken TLS peer identity validation and increase the risk of accepting a certificate for an unintended host. End-to-end exploitation is non-trivial in typical environments. This issue is fixed in versions 2.9.15 and 3.0.17.

Missing authorization in the JSON-RPC web services interface of Extreme Networks Switch Engine (EXOS) allows an authenticated, low-privileged (read-only) user to execute CLI show commands that are restricted to that role through the command line interface. Successful exploitation results in disclosure of sensitive information, including the device configuration and the password hashes of local accounts. Configuration, enable, and debug commands are not affected. Disclosed password hashes can be attacked offline, and a weak password could lead to administrative access to the device. This issue is fixed in Switch Engine 33.7.1-patch1-11, 33.1.100.133-patch1-9, and 32.7.4.15-patch1-11. Extreme Networks would like to thank Toàn Lê (GitHub: https://github.com/toanln-cov) for responsibly disclosing this vulnerability and for working with our PSIRT team through coordinated disclosure.

On affected platforms running Arista EOS with IEEE 802.1X authentication and MACsec using dynamically derived keys, sensitive authentication information may be recorded in diagnostic data during a Smart Switch Upgrade (SSU). An attacker with administrative access on the device who obtains the affected diagnostic data could recover sensitive authentication information. This could potentially compromise the confidentiality and integrity of traffic protected by MACsec on the affected link. The vulnerability is only exposed during and after an SSU reload where an active 802.1X session used for MACsec is present.
