An Improper Restriction Of Operations Within The Bounds Of A Memory Buffer issue was discovered in Advantech WebAccess versions prior to V8.220170817. Researchers have identified multiple vulnerabilities that allow invalid locations to be referenced for the memory buffer, which may allow an attacker to execute arbitrary code or cause the system to crash.
An Improper Authentication issue was discovered in Advantech WebAccess versions prior to V8.220170817. Specially crafted requests allow a possible authentication bypass that could allow remote code execution.
A stack-based buffer overflow issue was discovered in Advantech WebAccess versions prior to V8.220170817. Researchers have identified multiple vulnerabilities where there is a lack of proper validation of the length of user-supplied data prior to copying it to a stack-based buffer, which could allow an attacker to execute arbitrary code under the context of the process.
An Externally Controlled Format String issue was discovered in Advantech WebAccess versions prior to V8.220170817. String format specifiers based on user provided input are not properly validated, which could allow an attacker to execute arbitrary code.
A heap-based buffer overflow issue was discovered in Advantech WebAccess versions prior to V8.220170817. Researchers have identified multiple vulnerabilities where there is a lack of proper validation of the length of user-supplied data prior to copying it to the heap-based buffer, which could allow an attacker to execute arbitrary code under the context of the process.
An Incorrect Privilege Assignment issue was discovered in Advantech WebAccess versions prior to V8.220170817. A built-in user account has been granted a sensitive privilege that may allow a user to elevate to administrative privileges.
An Incorrect Permission Assignment for Critical Resource issue was discovered in Advantech WebAccess versions prior to V8.220170817. Multiple files and folders with ACLs that affect other users are allowed to be modified by non-administrator accounts.
An Uncontrolled Search Path Element issue was discovered in Advantech WebAccess versions prior to V8.220170817. A maliciously crafted dll file placed earlier in the search path may allow an attacker to execute code within the context of the application.
A SQL Injection issue was discovered in Advantech WebAccess versions prior to V8.220170817. By submitting a specially crafted parameter, it is possible to inject arbitrary SQL statements that could allow an attacker to obtain sensitive information.
