Pax Technology PAXSTORE v7.0.8_20200511171508 and lower is affected by XML External Entity (XXE) injection. An authenticated attacker can compromise the private keys of a JWT token and reuse them to manipulate the access tokens to access the platform as any desired user (clients and administrators).

Pax Technology PAXSTORE v7.0.8_20200511171508 and lower is affected by incorrect access control where password revalidation in sensitive operations can be bypassed remotely by an authenticated attacker through requesting the endpoint directly.

Pax Technology PAXSTORE v7.0.8_20200511171508 and lower is affected by incorrect access control that can lead to remote privilege escalation. PAXSTORE marketplace endpoints allow an authenticated user to read and write data not owned by them, including third-party users, application and payment terminals, where an attacker can impersonate any user which may lead to the unauthorized disclosure, modification, or destruction of information.

Pax Technology PAXSTORE v7.0.8_20200511171508 and lower is affected by an information disclosure vulnerability. Through the PUK signature functionality, an administrator will not have access to the current p12 certificate and password. When accessing this functionality, the administrator has the option to replace the current certificate and it is not possible to view the certificate password (p12) already deployed on the platform. The replacement p12 certificate returns to users in base64 with its password, which can be accessed by non-administrator users.

Pax Technology PAXSTORE v7.0.8_20200511171508 and lower is affected by a token spoofing vulnerability. Each payment terminal has a session token (called X-Terminal-Token) to access the marketplace. This allows the store to identify the terminal and make available the applications distributed by its reseller. By intercepting HTTPS traffic from the application store, it is possible to collect the request responsible for assigning the X-Terminal-Token to the terminal, which makes it possible to craft an X-Terminal-Token pretending to be another device. An attacker can use this behavior to authenticate its own payment terminal in the application store through token impersonation.

PAX A930 device with PayDroid_7.1.1_Virgo_V04.3.26T1_20210419 can allow a root privileged attacker to install unsigned packages. The attacker must have shell access to the device and gain root privileges in order to exploit this vulnerability.

PAX A930 device with PayDroid_7.1.1_Virgo_V04.3.26T1_20210419 can allow the execution of specific command injections on selected binaries in the ADB daemon shell service. The attacker must have physical USB access to the device in order to exploit this vulnerability.

PAX A930 device with PayDroid_7.1.1_Virgo_V04.3.26T1_20210419 can allow an unauthorized attacker to perform privileged actions through the execution of specific binaries listed in ADB daemon. The attacker must have physical USB access to the device in order to exploit this vulnerability.

PAX A930 device with PayDroid_7.1.1_Virgo_V04.3.26T1_20210419 can allow an attacker to gain root access through command injection in systool client. The attacker must have shell access to the device in order to exploit this vulnerability.

PAX A930 device with PayDroid_7.1.1_Virgo_V04.5.02_20220722 can allow an attacker to gain root access by running a crafted binary leveraging an exported function from a shared library. The attacker must have shell access to the device in order to exploit this vulnerability.

PAX A930 device with PayDroid_7.1.1_Virgo_V04.5.02_20220722 can allow the execution of arbitrary commands by using the exec service and including a specific word in the command to be executed. The attacker must have physical USB access to the device in order to exploit this vulnerability.

PAX Technology A930 PayDroid_7.1.1_Virgo_V04.5.02_20220722 allows attackers to compile a malicious shared library and use LD_PRELOAD to bypass authorization checks.

PAX Android based POS devices with PayDroid_8.1.0_Sagittarius_V11.1.45_20230314 or earlier can allow the signed partition overwrite and subsequently local code execution via hidden command. The attacker must have physical USB access to the device in order to exploit this vulnerability.

PAX A920Pro/A50 devices with PayDroid_8.1.0_Sagittarius_V11.1.50_20230614 or earlier can allow local code execution via parameter injection by bypassing the input validation when flashing a specific partition. The attacker must have physical USB access to the device in order to exploit this vulnerability.

PAX Android based POS devices with PayDroid_8.1.0_Sagittarius_V11.1.50_20230614 or earlier can allow the execution of arbitrary commands with system account privilege by shell injection starting with a specific word. The attacker must have shell access to the device in order to exploit this vulnerability.

PAX Android based POS devices with PayDroid_8.1.0_Sagittarius_V11.1.50_20230614 or earlier can allow for command execution with high privileges by using malicious symlinks. The attacker must have shell access to the device in order to exploit this vulnerability.

PAX A920 device allows to downgrade bootloader due to a bug in its version check. The signature is correctly checked and only bootloader signed by PAX can be used.  The attacker must have physical USB access to the device in order to exploit this vulnerability.
