Secure Software for the Internet of Things

Allegro Software Urges Manufacturers
To Maintain Firmware for Highest Level of Embedded Device Security

CVE-2014-9222 and CVE-2014-9223 security concerns addressed almost a decade ago

 

BOXBOROUGH, MA December 19, 2014 – Allegro Software, a leading supplier of Internet component software for embedded devices, urges manufacturers of network enabled embedded products to maintain the latest release of component software in their products. Since standards based protocols continue to evolve and new networking security concerns continue to be uncovered and addressed, using the latest version of Allegro’s software components is the way that manufacturers can be assured that their products include robust security and the highest levels of compatibility with standards.

 

An example is the case of the CVE-2014-9222 and CVE-2014-9223 vulnerabilities (also known as Misfortune Cookie). These vulnerabilities were discovered in the RomPager embedded web server version 4.07, which was released in 2002. Allegro had previously identified, fixed, and released updated software components that addressed these vulnerabilities. RomPager version 4.34, which resolved these vulnerabilities, was provided to Allegro Software customers in 2005. Allegro has continued to provide updates and enhancements to the RomPager software, and the latest available version is 5.40.

 

Unfortunately, not all manufacturers using Allegro Software products have updated their devices with the latest RomPager software component. In some cases, manufacturers continue to make and sell products with software components that are over 13 years old, which can expose products to security concerns. Allegro Software is a software component supplier to product manufacturers. Allegro Software does not have the ability to upgrade or patch our customer’s manufactured products. If you have a product that is affected by the above security concerns, please contact the product manufacturer to obtain a firmware update.

 

“MISFORTUNE COOKIE” VULNERABILITY IN VERSION 4.07 – CVE-2014-9222
In early 2002, Allegro Software released the RomPager (v4.07) embedded web server which added support for browser cookies. After the v4.07 release, Allegro identified and fixed a security issue related to the implementation of cookies with the RomPager (v4.34) release in mid 2005. Since 2005, all new and existing customers under Allegro’s software maintenance program have been provided the latest software so that they can update their products and resolve this security concern.

 

DIGEST BUFFER OVERFLOW VULNERABILITY IN VERSION 4.07 – CVE-2014-9223
RomPager Version 4.07 also included a Digest Authentication buffer overflow vulnerability. This security issue was also identified and addressed in the RomPager 4.34 software release.

 

ONGOING DEVELOPMENT
Since version 4.34, Allegro Software has continued to invest in embedded device security with ongoing development of our existing products and creation of new products aimed at secure Internet connectivity. These investments have included the creation of the Allegro Cryptography Engine (ACE), which has received FIPS 140-2 validation (http://csrc.nist.gov/groups/STM/cmvp/documents/140-1/1401val2013.htm#2048). Allegro’s suite of Advanced Edition toolkits with IPv4/IPv6 capabilities have been fully integrated with ACE and is targeted at next-generation embedded systems connectivity with advanced security requirements. “For over 18 years, Allegro has focused on delivering highly reliable software components for embedded systems found in consumer electronics, medical devices, industrial-control applications, military applications and more.” says Bob Van Andel, President of Allegro. “We take embedded device security seriously and want our customer partners to do the same. We strongly urge manufacturers to maintain their firmware with the latest software components to deliver the highest level of Internet communications compatibility and embedded device security to the end customer.”

Embedded FIPS 140-2 Cryptography

FIPS 140-2 Level 2 Logo

The Allegro Cryptography Engine (ACE) is a platform independent, high performance, resource sensitive, embedded  FIPS 140-2 Validated cryptography engine specifically engineered for the rigors of embedded computing. ACE enables OEM manufacturers to add sophisticated FIPS approved encryption technology to their designs and dramatically speed the development cycle. The ACE cryptography library is designed to meet the requirements needed for FIPS 140-2 validation.

ACE

Embedded systems are appearing in virtually all industries with the capability to communicate independently. The rapid adoption and deployment of modern communication technologies have enabled new applications in healthcare, military applications, energy management, consumer devices and many other areas. With these capabilities, comes the need for embedded device security. Any network-enabled device must be considered as a potential target for malicious intent. Encryption of sensitive data while in motion or at rest is a key component to thwarting malicious attacks and reducing risk.

ACE is a cryptographic library module for embedded computing systems that provides validated software implementations of FIPS-approved algorithms for the calculation of message digests, digital signature creation and verification, bulk encryption and decryption, key generation and key exchange. Used stand-alone or pre-integrated with Allegro's Secure IoT Suite, ACE provides CAVP validated implementations of sophisticated FIPS approved encryption algorithms for use in embedded systems. In 2005, the National Security Agency (NSA) defined a set of cryptographic algorithms that when used together, are the preferred method for assuring the security and integrity of information passed over public networks such as the Internet. Today, Suite B is globally recognized as an advanced standard for cryptography that defines algorithms and strengths for encryption, hashing, calculating digital signatures and key exchange. ACE includes a platform independent, CAVP validated implementation of the NSA Suite B defined suite of cryptographic algorithms. ACE is delivered as ANSI C source.

Securing Data In Motion

Many IoT applications often collect and correlate valuable sensitive information at the edge of the Internet and routinely transmit it to servers in the cloud securely. TLS and DTLS are the “defacto” standards for keeping data secure when communicating with servers in the cloud. Allegro’s RomSTL, embedded TLS, and DTLS toolkit, tightly integrates FIPS validated cryptography with a standards-based, embedded implementation of TLS/DTLS to keep your data secure while in motion. RomTLS is additionally integrated to make use of ACE’s support of Suite B algorithms (RFC 6460).

Securing Data At Rest

Allegro’s secure data-at-rest solution is tightly integrated with ACE validated FIPS 140-2 cryptography. Before offloading data to cloud-based applications, any sensitive information stored by IoT devices faces numerous threats and risks of unintentional exposure. Adding data encryption to the transmission process has been the traditional method for reducing this risk. However, simply encrypting data transmissions doesn’t fully address many of the threats aimed at recovering small segments of data or potentially the entire collection. Allegro's Secure IoT Suite provides IoT design engineers the ability to proactively address the threat surface created when storing sensitive data on persistent media. Rather than encrypting data at a volume or drive level where exposing a single set of keys potentially compromises a significant amount of sensitive data, Allegro’s secure data-at-rest solution encrypts information at the file level.

ACE can be used stand-alone or pre-integrated with Allegro’s Secure IoT Suite.
