Symantec has fixed a flaw in its Enterprise Security Manager (ESM) solution that allows an attacker to take complete control of a PC.In an advisory released Thursday, Symantec said that all versions of the product are vulnerable to the flaw, which exists in the ESM agent remote upgrade interface.
The program’s agent accepts remote upgrade requests from any entity that understands the upgrade protocol, not verifying that the requests are from a trusted source, as it should, according to the advisory.
A hacker, assuming they have knowledge of the agent’s protocol, can take control of a PC by infecting it with malicious software.
The anti-virus giant was not aware of any exploits in the wild, according to Symantec.
The flaw is exploitable from both remote and local locations, according to a Friday advisory from FrSIRT (the French Security Incident Response Team), which ranked the flaw as "high risk."
