    pupnp: Denial of service via blocking DNS resolution in parse_uri()/GENA callback parsing

    pupnp is an SDK for development of UPnP device and control point applications. Prior to 22.0.4, parse_hostport in upnp/src/genlib/net/uri/uri.c synchronously calls getaddrinfo while parse_uri is processing attacker-supplied hostnames from inbound HTTP request targets in upnp/src/genlib/net/http/httpparser.c and GENA SUBSCRIBE CALLBACK headers handled by create_url_list in upnp/src/gena/gena_device.c. A remote unauthenticated peer can choose a slow or nonresponsive hostname and block a bounded miniserver worker for the resolver timeout, allowing a small number of requests to exhaust the thread pool and deny UPnP service. This issue is fixed in

    pupnp: Integer truncation in HTTP Content-Length parsing enables request smuggling

    pupnp is an SDK for development of UPnP device and control point applications. Prior to 2.0.2, raw_to_int in upnp/src/genlib/net/http/httpparser.c parses Content-Length with strtol and casts the resulting long to a 32-bit int before the caller stores it as unsigned int. On LP64 systems, values greater than INT_MAX can truncate or wrap, so the HTTP parser can accept a body length different from the declared value. A remote adjacent-network peer can use the resulting parser disagreement to leave bytes to be interpreted as another request in persistent or proxied contexts, or can make a worker wait for an extremely large body and cause denial of

    High · CVSS 7.5EPSS 0.34%Fix available

    libupnp chunked HTTP bodies can bypass g_maxContentLength and be fully buffered

    pupnp is an SDK for development of UPnP device and control point applications. Prior to 2.0.2, Transfer-Encoding: chunked causes the HTTP parser in upnp/src/genlib/net/http/httpparser.c to leave parser->content_length at zero while parser_parse_chunky_entity and parser_parse_chunky_body accumulate decoded bytes in parser->msg.entity. The g_maxContentLength checks in http_RecvMessage in upnp/src/genlib/net/http/httpreadwrite.c therefore reject oversized numeric Content-Length bodies but do not enforce the same limit on decoded chunked bodies. A remote peer that can reach a SOAP, GENA, miniserver, or control-point HTTP response path can make th

    pupnp: NULL pointer dereference in ixmlNode_compare crashes on non-namespaced attributes

    pupnp is an SDK for development of UPnP device and control point applications. Prior to 2.0.2, ixmlNode_compare in ixml/src/node.c passes the nullable nodeValue, namespaceURI, prefix, and localName fields directly to strcmp. Non-namespaced attributes created by ixmlDocument_createAttribute legitimately leave those fields NULL. When ixmlElement_removeAttributeNode compares two distinct attribute objects with the same nodeName through find_condition_node, the pointer-identity shortcut does not apply and the comparison dereferences NULL, causing a process crash when application handling of attacker-controlled XML reaches this path. This issue is

    pupnp: Incomplete fix for CVE-2021-28302: recursive DOM functions cause stack overflow

    pupnp is an SDK for development of UPnP device and control point applications. Prior to 2.0.0, multiple ixml DOM traversal functions process deeply nested XML with unbounded recursion. The iterative XML parser accepts the document, but ixmlPrintDomTreeRecursive in ixml/src/ixml.c and ixmlNode_getElementsByTagNameRecursive, ixmlNode_getElementsByTagNameNSRecursive, ixmlNode_cloneNodeTreeRecursive, and ixmlNode_isAncestor in ixml/src/node.c recurse over firstChild and nextSibling links. An unauthenticated peer on the local network can supply deeply nested XML through a SOAP request, exhaust a service thread's stack, and crash the UPnP service.

    pupnp: Port truncation via atoi() cast in parse_uri() allows SSRF port confusion

    pupnp is an SDK for development of UPnP device and control point applications. Prior to version 1.18.5, pupnp is vulnerable to SRRF port confusion due to port truncation via atoi() cast in parse_uri(). This issue has been patched in version 1.18.5.
