Advantech WISE-DeviceOn Server versions prior to 5.4 contain a hard-coded cryptographic key vulnerability. The product uses a static HS512 HMAC secret for signing EIRMMToken JWTs across all installations. The server accepts forged JWTs that need only contain a valid email claim, allowing a remote unauthenticated attacker to generate arbitrary tokens and impersonate any DeviceOn account, including the root super admin. Successful exploitation permits full administrative control of the DeviceOn instance and can be leveraged to execute code on managed agents through DeviceOn’s remote management features.

Successful exploitation of the SQL injection vulnerability could allow an unauthenticated remote attacker to execute arbitrary SQL commands on the vulnerable service when it is exposed to the Internet, potentially affecting data confidentiality, integrity, and availability. Users and administrators of affected product versions are advised to update to the latest versions immediately.

As per Upstream advisory:

The internal |fmtstr| function used in processing a "%s" format string in the BIOprintf functions could overflow while calculating the length of a string and cause an OOB read when printing very long strings.

Additionally the internal |doaproutch| function can attempt to write to an OOB memory location (at an offset from the NULL pointer) in the event of a memory allocation failure. In 1.0.2 and below this could be caused where the size of a buffer to be allocated is greater than INTMAX. E.g. this could be in processing a very long "%s" format string. Memory leaks can also occur.

These issues will only occur on certain platforms where sizeof(sizet) > sizeof(int). E.g. many 64 bit systems. The first issue may mask the second issue dependent on compiler behaviour. These problems could enable attacks where large amounts of untrusted data is passed to the BIOprintf functions. If applications use these functions in this way then they could be vulnerable. OpenSSL itself uses these functions when printing out human-readable dumps of ASN.1 data. Therefore applications that print this data could be vulnerable if the data is from untrusted sources. OpenSSL command line applications could also be vulnerable where they print out ASN.1 data, or if untrusted data is passed as command line arguments.

Libssl is not considered directly vulnerable. Additionally certificates etc received via remote connections via libssl are also unlikely to be able to trigger these issues because of message size limits enforced within libssl.

This issue affects OpenSSL versions 1.0.2 and 1.0.1.

OpenSSL 1.0.2 users should upgrade to 1.0.2g OpenSSL 1.0.1 users should upgrade to 1.0.1s

This issue was reported to OpenSSL on February 23rd by Guido Vranken. The fix was developed by Matt Caswell of the OpenSSL development team.

It was found that doaproutch function in crypto/bio/bprint.c in OpenSSL 1.0.1 before 1.0.1s and 1.0.2 before 1.0.2g does not verify that a certain memory allocation succeeds, which allows remote attackers to cause a denial of service (out-of-bounds write or memory consumption) or possibly have unspecified other impact via a long string, as demonstrated by a large amount of ASN.1 data. This issues is different than CVE-2016-0799.
