No technological development is completely exempt from any security flaw. A report by participants of a hacking course mentions the finding of at least ten critical vulnerabilities in the Siemens SiNVR 3 video surveillance system.
The aforementioned system is affected by various exploitable flaws ranging from SQL injections, XSS attacks and input validation errors, among others. Below is a brief explanation of the most dangerous vulnerabilities that were found.
Path traversal: This is a medium severity vulnerability that
exists due to an input validation error when processing directory cross-streams.
A remote threat actor might send a malicious HTTP request to read arbitrary
files on the system.
This flaw was tracked as CVE-2019-19290 and at the
moment there are no patches or possible workarounds, mention members of the
Sensitive information storage in clear text: This medium severity flaw, tracked
exists due to a feature enabled by default on the affected product. A remote
hacker could access highly sensitive information without encountering major
obstacles in the system if the FTP service is enabled.
SQL Injection: Tracked as CVE-2019-19292, it allows
remote hackers to send specially designed requests to the affected application
to execute arbitrary SQL commands within the application database.
This is a high severity flaw, as its successful
exploitation allows threat actors to read, delete or modify the data and gain
control of the affected database. As with previous reports, there are no known
methods to mitigate the risk of exploitation yet.
XSS Attacks: This flaw, tracked as CVE-2019-19293, would
allow remote hackers to perform XSS
attacks by redirecting victims with specially designed links to then
execute arbitrary code in the target user’s browser.
If exploited, this flaw would allow phishing
attacks, extract sensitive information, show malvertising, among other
malicious activities; it is worth mentioning that the risk of exploitation of
this flaw is low, experts report the hacking course.
Insufficient Logging: Tracked as CVE-2019-19295, this vulnerability
allows remote hackers to compromise the target system by performing various
malicious actions in a stealth manner. There is no known mitigation.
Cryptographic issues: This vulnerability exists due to
the weakness of encryption in the affected product, and allows remote threat
actors to decrypt passwords on the system. The fault was tracked as CVE-2019-19229.
The International Institute of Cyber Security (IICS)
reminds users of affected deployments that there are no security
patches or workarounds available, so it is recommended to stay on top of the
official announcements of the company.
