February 2023 Aspera Vulnerability Patches
At the beginning of February 2023, Aspera announced a vulnerability in some of the Aspera products. This includes:
- IBM Aspera Orchestrator – Linux and Windows (Versions 4.0.0 and earlier)
- IBM Aspera faspio Gateway – Linux and Windows (Versions 1.2.1 and earlier)
- IBM Aspera Faspex – Linux and Windows (Versions 4.4.1 and earlier)
Below, we will go over some of the vulnerability details and the links to the patches to protect against them.
IBM Aspera Orchestrator
For versions 4.0.0 and earlier, there were a few vulnerabilities detected with the OpenSSL.
For CVE-2021-23839, the OpenSSL could provide weaker-than-expected security due to an incorrect SSLv2 rollback protection that allows for inversion of the logic during a padding check.
For CVE-2021-23840, the OpenSSL is vulnerable to a denial of service caused by an integer overflow in CipherUpdate. An attacker could exploit this vulnerability to cause the application to crash.
For CVE-2021-23841, the OpenSSL is also vulnerable to a denial of service caused by a NULL pointer dereference in the X509 function. This could also lead to an attacker exploiting this vulnerability, causing the application to crash.
IBM Aspera faspio Gateway
For versions 1.2.1 and earlier, there were a few vulnerabilities with the OpenSSL that affected IBM Aspera faspio Gateway.
For CVE-2022-3602, the OpenSSL is vulnerable to a stack-based buffer overflow, which is caused by improper bounds checking during X.509 certificate verification. A remote attacker could overflow a buffer and execute arbitrary code or cause the application to crash if using a specially-crafted email address.
For CVE-2022-3786, the OpenSSL is vulnerable to a denial of service caused by a stack-based buffer overflow. With a specialty-crafted email address, a remote attacker could exploit this vulnerability to cause a TLS client to crash.
To fix this as soon as possible, IBM Aspera faspio Gateway users should download the latest version 1.3.1 for their proper platform:
