New patches resolve issues on a popular storage app that could lead to SQL injection attacks or cause a DoS.

CA has fixed a number of vulnerabilities reported in its BrightStor Hierarchical Storage Manager application that can be used by hackers to launch SQL injection attacks, cause a denial of service condition, or compromise a vulnerable system. BrightStor is an application used to create a tiered storage solution for enterprises, and caches frequently-used files on hard drives for fast access, while storing files used more infrequently on tape.
Based in Islandia, N.Y., CA, long entrenched as a market leader in storage management software, has a 15-year history in this sector—more substantial than well-known competitors EMC, NetApp and Symantec.
According to iDefense Labs, which reported the flaw to CAremote exploitation of multiple buffer overflow vulnerabilities allows attackers to execute arbitrary code with SYSTEM privileges. The issue lies within various command handlers in the CsAgent service, which listens on TCP port 2000. There are eleven command handlers that contain one or more stack-based buffer overflow vulnerabilities each. All of these vulnerabilities are simple sprintf calls that overflow fixed size stack buffers with attacker supplied data, the iDefense advisory states.

In addition, there are five command handlers that are susceptible to integer overflow vulnerabilities, and the function responsible for reading in and dispatching a request to the appropriate handler contains an integer overflow vulnerability as well. In each case, a 32-bit integer is taken from the packet and either added or multiplied to determine how much memory to allocate, the iDefense advisory states. "When these calculations cause an integer wrap, a heap buffer of insufficient size is allocated," the advisory continues. "Later, a heap overflow occurs when filling the buffer." A hacker would have to establish a TCP session on port 200 to exploit this vulnerability, and no authentication is required. All of the issues, rated moderately critical by Danish security company Secunia, are addressed in the latest version of the product, version r11.6.
