CVE-2021-38449

Some API functions permit by-design writing or copying data into a given buffer. Since the client controls these parameters, an attacker could rewrite the memory in any location of the affected product.

CVE-2021-38453

Some API functions allow interaction with the registry, which includes reading values as well as data modification.

CVE-2021-38455

The affected product’s OS Service does not verify any given parameter. A user can supply any type of parameter that will be passed to inner calls without checking the type of the parameter or the value.

CVE-2021-38465

The webinstaller is a Golang web server executable that enables the generation of an Auvesy image agent. Resource consumption can be achieved by generating large amounts of installations, which are then saved without limitation in the temp folder of the webinstaller executable.

CVE-2021-38451

The affected product’s proprietary protocol CSC allows for calling numerous function codes. In order to call those function codes, the user must supply parameters. There is no sanitation on the value of the offset, which allows the client to specify any offset and read out-of-bounds data.

CVE-2021-38457

The server permits communication without any authentication procedure, allowing the attacker to initiate a session with the server without providing any form of authentication.

CVE-2021-38479

Many API function codes receive raw pointers remotely from the user and trust these pointers as valid in-bound memory regions. An attacker can manipulate API functions by writing arbitrary data into the resolved address of a raw pointer.

CVE-2021-38461

The affected product uses a hard-coded blowfish key for encryption/decryption processes. The key can be easily extracted from binaries.

CVE-2021-38463

The affected product does not properly control the allocation of resources. A user may be able to allocate unlimited memory buffers using API functions.

CVE-2021-38475

The database connection to the server is performed by calling a specific API, which could allow an unprivileged user to gain SYSDBA permissions.

CVE-2021-38471

There are multiple API function codes that permit data writing to any file, which may allow an attacker to modify existing files or create new files.

CVE-2021-38481

The scheduler service running on a specific TCP port enables the user to start and stop jobs. There is no sanitation of the supplied JOB ID provided to the function. An attacker may send a malicious payload that can enable the user to execute another SQL expression by sending a specific string.

CVE-2021-38459

The data of a network capture of the initial handshake phase can be used to authenticate at a SYSDBA level. If a specific .exe is not restarted often, it is possible to access the needed handshake packets between admin/client connections. Using the SYSDBA permission, an attacker can change user pas...

CVE-2021-38473

The affected product’s code base doesn’t properly control arguments for specific functions, which could lead to a stack overflow.

CVE-2021-38467

A specific function code receives a raw pointer supplied by the user and deallocates this pointer. The user can then control what memory regions will be freed and cause use-after-free condition.

CVE-2021-38477

There are multiple API function codes that permit reading and writing data to or from files and directories, which could lead to the manipulation and/or the deletion of files.

CVE-2021-38469

Many of the services used by the affected product do not specify full paths for the DLLs they are loading. An attacker can exploit the uncontrolled search path by implanting their own DLL near the affected product’s binaries, thus hijacking the loaded DLL.
