A buffer overflow vulnerability has been found in XAMPP affecting version 8.2.4 and earlier. An attacker could execute arbitrary code through a long file debug argument that controls the Structured Exception Handler (SEH).
The installer in XAMPP through 8.1.12 allows local users to write to the C:\xampp directory. Common use cases execute files under C:\xampp with administrative privileges.
Xampp for Windows v8.1.4 and below was discovered to contain insecure permissions for its install directory, allowing attackers to execute arbitrary code via overwriting binaries located in the directory.
An issue was discovered in XAMPP before 7.2.29, 7.3.x before 7.3.16 , and 7.4.x before 7.4.4 on Windows. An unprivileged user can change a .exe configuration in xampp-contol.ini for all users (including admins) to enable arbitrary command execution.
XAMPP installs multiple packages with insecure default passwords, which makes it easier for remote attackers to obtain access via (1) the "lampp" default password for the "nobody" account within the included ProFTPD installation, (2) a blank default password for the "root" account within the included MySQL installation, (3) a blank default password for the "pma" account within the phpMyAdmin installation, and possibly other unspecified passwords. NOTE: this was originally reported as a problem in DFLabs PTK, but this issue affects any product that is installed within the XAMPP environment, and should not be viewed as a vulnerability within that product. NOTE: DFLabs states that PTK is intended for use in a laboratory with "no contact from / to internet."
Multiple unquoted Windows search path vulnerabilities in Apache Friends XAMPP 1.5.2 might allow local users to gain privileges via a malicious program file in %SYSTEMDRIVE%, which is run when XAMPP attempts to execute (1) FileZillaServer.exe, (2) mysqld-nt.exe, (3) Perl.exe, or (4) xamppcontrol.exe with an unquoted "Program Files" pathname.
