CVE-2007-2336 in NaviCOPA Web Server
Summary
by MITRE
Unspecified vulnerability in InterVations NaviCOPA Web Server 2.01 20070323 allows remote attackers to cause a denial of service (daemon crash) via crafted HTTP requests, as demonstrated by long requests containing \A characters, probably a different issue than CVE-2006-5112 and CVE-2007-1733. NOTE: the provenance of this information is unknown; the details are obtained solely from third party information.

The vulnerability described in CVE-2007-2336 represents a denial of service flaw within the InterVations NaviCOPA Web Server version 2.01 build 20070323. This issue manifests when remote attackers submit specially crafted HTTP requests that trigger a daemon crash, effectively rendering the web server unavailable to legitimate users. The specific trigger involves long HTTP requests containing \A characters, which suggests a parsing or buffer handling weakness in the server's request processing logic. The vulnerability is classified as unspecified, indicating that the exact technical mechanism remains unclear, though the impact is well-documented through demonstration of the crash condition.
The technical exploitation of this vulnerability demonstrates a classic buffer overflow or input validation weakness that affects the web server's ability to process malformed HTTP requests properly. The presence of \A characters in the request payload likely triggers a specific parsing path within the server software that leads to memory corruption or improper state handling. This type of vulnerability falls under the broader category of input validation failures that can be exploited to cause system instability. The fact that this vulnerability appears to be distinct from CVE-2006-5112 and CVE-2007-1733 indicates that it represents a separate code path or implementation flaw within the NaviCOPA Web Server software.
From an operational perspective, this vulnerability poses a significant risk to organizations relying on the NaviCOPA Web Server for critical web services. A remote attacker capable of sending malicious HTTP requests can effectively disrupt service availability, causing downtime that may impact business operations and user access to web applications. The remote nature of the attack means that adversaries do not require physical access or local system privileges to exploit this vulnerability, making it particularly dangerous in networked environments. The daemon crash resulting from this vulnerability can lead to complete service interruption until manual intervention or system restart occurs, potentially causing cascading effects in dependent systems that rely on the web server functionality.
Security mitigations for this vulnerability should focus on implementing proper input validation and request sanitization mechanisms within the web server configuration. Organizations should consider applying available patches or updates from InterVations if they exist, as well as implementing network-level protections such as intrusion detection systems that can identify and block suspicious HTTP request patterns. The vulnerability's characteristics align with CWE-121, which describes buffer overflow conditions, and may also relate to CWE-122, which covers heap-based buffer overflows. From an ATT&CK framework perspective, this vulnerability could be categorized under T1499.004 for network denial of service and potentially T1071.004 for application layer protocol usage, as it specifically targets HTTP request processing. Organizations should also consider implementing rate limiting and request size restrictions to prevent exploitation of similar input validation weaknesses in their web server configurations.
