TITLE

Fuji Electric V-Server Buffer error vulnerability

Trust: 0.8

sources: JVNDB: JVNDB-2018-010431

DESCRIPTION

Fuji Electric V-Server 4.0.3.0 and prior, A stack-based buffer overflow vulnerability has been identified, which may allow remote code execution. Fuji Electric V-Server Contains a buffer error vulnerability.Information is obtained, information is altered, and service operation is disrupted (DoS) There is a possibility of being put into a state. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file.The specific flaw exists within the parsing of a VPR file. The issue results from the lack of proper validation of the length of user-supplied data prior to copying it to a fixed-length stack-based buffer. An attacker can leverage this vulnerability to execute code under the context of the process. Fuji Electric V-Server VPR is a data collection software from Fuji Electric of Japan. Fuji Electric V-Server is prone to multiple security vulnerabilities: 1. A use-after-free vulnerability 2. Multiple untrusted pointer dereference remote code-execution vulnerabilities 3. Multiple out-of-bounds write vulnerabilities 5. An integer underflow vulnerability 6. An out-of-bounds read vulnerability 7. V-Server 4.0.3.0 and prior are vulnerable
