Description

A weakness has been identified in DefaultFuction Customer-Relationship-Management-In-C-Project 2.0. Impacted is the function gets of the component Customer Search Module. This manipulation causes stack-based buffer overflow. The attack may be initiated remotely. The exploit has been made available to the public and could be used for attacks. The project confirms, that "it’s being processed".

  "executiveSummary": "A critical vulnerability has been identified in DefaultFuction Customer-Relationship-Management-In-C-Project version 2.0, specifically within the gets function of the Customer Search Module. This security flaw involves a stack-based buffer overflow vulnerability that can be exploited remotely by unauthorized malicious actors. The presence of publicly available exploit code significantly escalates the risk profile, allowing potential attackers to leverage the flaw without prior authentication.\nThe vulnerability resides in the insecure handling of input data within the customer search functionality. When an attacker submits maliciously crafted input that exceeds the allocated buffer size, it leads to memory corruption on the stack. This can ultimately result in arbitrary code execution, system crashes, or denial of service conditions, posing severe integrity and availability risks to the host environment.\nGiven that the vulnerability is remotely exploitable and public exploits exist, immediate defensive measures are critical. Although the vendor has acknowledged the issue and stated that it is being processed, an official vendor patch may not yet be universally available, necessitating alternative hardening and remediation strategies to protect vulnerable deployments.",
  "technicalDetails": "The vulnerability is classified as a stack-based buffer overflow, originating from the improper implementation of input ingestion within the Customer Search Module of DefaultFuction Customer-Relationship-Management-In-C-Project version 2.0. Specifically, the flaw is rooted in the usage of the unsafe gets function to capture user-supplied data.\nThe gets function is inherently insecure because it reads characters from standard input and stores them in a character array without performing any bounds checking on the size of the input. Consequently, if a user or remote attacker provides a data string that is larger than the predefined destination buffer allocated on the stack, the excess data overflows the buffer boundaries.\nDuring the exploitation process, this overflow overwrites adjacent stack memory structures, which typically include critical control data such as saved frame pointers and return addresses. By carefully constructing the input payload, an attacker can manipulate the execution flow of the application when the function attempts to return, redirecting processor execution to malicious shellcode or arbitrary instructions embedded within the payload.\nThe attack vector is network-based, allowing remote adversaries to interact with the Customer Search Module over communication channels where input is parsed by the vulnerable gets implementation. The vulnerability requires no prior authentication or specialized privileges, lowering the complexity barrier for successful exploitation.\nThe post-exploitation impact includes potential remote code execution under the security context of the running application process, data tampering, and application destabilization through denial of service. The availability of public exploits accelerates the transition from theoretical risk to active exploitation in the wild."
