CVE Vulnerability Catalog

When mongosqld is configured with a client certificate authority file, the listener requests a client certificate during the TLS handshake but does not require one, so a client that presents no certificate is still accepted. In deployments that rely on client certificates as the sole means of identifying users, a remote party with network access to the listener can therefore establish a session and read the MongoDB data exposed through the connector.

An unauthenticated party able to reach the port of a MongoDB Connector for BI (mongosqld) instance may generate enough routine connection log activity to exhaust the storage backing the configured log path. When a log write or log rotation operation subsequently fails, the resulting error is not handled and the shared mongosqld process ends, ending service for all connected SQL clients. The process continues to end on startup until an operator restores available storage, and the diagnostic message explaining the condition is not recorded.

A database user able to create a view in a namespace that MongoDB Connector for BI samples can cause the schema-sampling routine to stop functioning by defining a view whose evaluation reliably fails. The sampling logic classifies the resulting server message as transient and, after the configured retries are exhausted, proceeds without a valid result, ending the schema refresh routine. The mongosqld process continues running without a usable schema, so SQL clients are unable to obtain results until an operator removes the view or excludes its namespace from sampling.

multer is a middleware for handling multipart/form-data in Node.js. A small multipart request containing two specially crafted text field names can cause an uncaught RangeError (Invalid array length) that terminates the Node.js process. The first field uses a very large numeric array index to allocate a maximum-length sparse array, and a second field then pushes past that length, which throws inside the append-field dependency and is not caught by multer. All versions before 2.3.0 are affected, and the issue is a remotely triggerable denial of service. The issue is fixed in multer 2.3.0. Upgrade to multer 2.3.0 to remediate.

multer before version 2.3.0 has a race condition vulnerability in file stream handling when an asynchronous fileFilter is used together with the fileSize limit. This allows bypassing the rejection of files exceeding the size limit.

multer is a middleware for handling multipart/form-data in Node.js. In version 2.2.0, when a disk-backed upload is aborted or truncated before the write stream finishes, multer's disk storage engine removes the visible file but does not close the underlying write file descriptor, leaving a deleted but still open descriptor. A remote attacker able to reach an upload route using the built-in disk storage can send repeated aborted or malformed multipart uploads, each one leaking a file descriptor and retaining disk blocks until the process exits, which can exhaust resources and cause a denial of service. The issue is fixed in multer 2.3.0, which closes the destination write stream on abnormal source termination and defers cleanup until the stream has closed. Upgrade to multer 2.3.0 to remediate.

A buffer overflow vulnerability exists in the embedded HTTP service in TL-WR841N v14 when processing multipart/form-data requests. Insufficient validation of an attacker-controlled boundary parameter may allow a remote unauthenticated attacker to submit a crafted request that corrupts memory by overwriting data beyond the bounds of an internal buffer.

A NULL pointer dereference vulnerability exists in TL-WR841N v14 in the UPnP service when processing SOAP state variable query requests. A specially crafted SOAP query may trigger unexpected termination or instability of the process hosting the UPnP service.

A NULL pointer dereference vulnerability exists in TL-WR841N v14 in the UPnP service when processing SOAP action requests. A specially crafted SOAP action request containing unexpected XML content may cause the UPnP daemon to terminate unexpectedly.

A pre-authentication stack-based buffer overflow vulnerability exists in the http_gdpr_decrypt function of TL-MR100 V3.20 due to insufficient bounds checking of encrypted requests to the /cgi/login endpoint. An adjacent unauthenticated attacker with access to the router's web management interface can trigger memory corruption and potentially achieve arbitrary code execution. Successful exploitation can overwrite saved control-flow data on the httpd process stack prior to authentication, resulting in a service crash or potential arbitrary code execution in the context of the affected process.

PrivateBin before version 2.0.5 has a vulnerability in Request::getRequestUri() which passes $_SERVER['REQUEST_URI'] through FILTER_SANITIZE_URL, not removing quotation marks, angle brackets, or apostrophes. The attacker-controlled value is then inserted into JSON-LD templates without JSON escaping, potentially allowing injection of data into application/ld+json responses.

Klever-Go is the Go implementation of the Klever blockchain protocol. Prior to 1.7.19, processPercentageRoyaltiesTransfer in core/kapp/accounts/accounts.go calls SubFromBalance after the split loop and after the royaltiesToPay <= 0 early return. computeSplitRoyalties rejects only when splitToPay > royaltiesToPay, so a valid PercentTransferPercentage = 10000 split consumes exactly 100 percent of the royalty pool, sets royaltiesToPay to zero, and returns before the source account is debited. The split recipient receives the full royaltyAmount while the sender pays nothing and the supply counter is not updated, allowing unbounded off-the-books inflation of the transferred KDA. A KDA owner must configure a TransferPercentage royalty with a 100 percent split, after which any holder's transfer of the asset triggers the mint; the sibling processFixedRoyaltiesTransfer path is not affected because it debits the source before distribution. This issue is fixed in version 1.7.19.

PrivateBin is an online pastebin where the server has zero knowledge of pasted data. Prior to 2.0.5, AttachmentViewer.setAttachment in js/privatebin.js uses getAttachmentMimeType to accept attacker-controlled MIME types and uses getBlobUrl to create a same-origin blob before setting attachmentLink's href for the Download attachment link. The SVG-only sanitization branch updates only the preview blob, so text/html, image/svg, application/xhtml+xml, and text/xml attachments can remain active in the download blob. On an instance with fileupload = true and a weakened, stripped, or absent Content Security Policy, an anonymous attacker can create such an attachment, and a victim who opens the link in a new tab causes inline JavaScript to execute in the PrivateBin origin. The script can read origin-scoped local storage and issue same-origin requests, including requests to applications co-hosted on the same domain. This issue is fixed in version 2.0.5.

Arc Enterprise versions 26.02.1 through 26.06.2 accept cluster join requests without authentication when clustering is enabled but no shared secret is configured. An attacker can become a trusted node, intercept requests, and alter cluster membership.

TOTOLINK T6 version 4.1.5cu.748_B20211015 has incorrect access control in the getTracerouteCfg function, allowing unauthenticated attackers to obtain traceroute diagnostic logs by sending a crafted POST request to /cgi-bin/cstecgi.cgi.

TOTOLINK T6 version 4.1.5cu.748_B20211015 has incorrect access control in the getTelnetCfg function, allowing unauthenticated attackers to obtain Telnet service enablement status information by sending a crafted POST request to /cgi-bin/cstecgi.cgi.

TOTOLINK T6 version 4.1.5cu.748_B20211015 has incorrect access control in the getWiFiApcliScan function, allowing unauthenticated attackers to trigger wireless scans and retrieve AP-client scan results by sending a crafted POST request to /cgi-bin/cstecgi.cgi.

TOTOLINK T6 version 4.1.5cu.748_B20211015 has incorrect access control in the getCloudSrvCheckStatus function, allowing unauthenticated attackers to obtain cloud firmware check status information by sending a crafted POST request to /cgi-bin/cstecgi.cgi.

TOTOLINK T6 version 4.1.5cu.748_B20211015 has incorrect access control in the getPortForwardRules function, allowing unauthenticated attackers to obtain port-forwarding rules by sending a crafted POST request to /cgi-bin/cstecgi.cgi.

IBM Cloud Pak for Data System 11.3.0.2 through Interim Fix 001 is vulnerable to a denial of service due to improper limitation of resources.
