Multiple Critical Vulnerabilities Affected Huawei’s Web Application that Allows Hackers To Execute Code

Security researchers from Swascan discovered critical multiple vulnerabilities in Huawei web application that could be exploited by Cybercriminals to access sensitive information.

Totally three vulnerabilities were identified, and the vulnerabilities ranked as critical that could impact regular operations if exploited.

Vulnerabilities Discovered in Huawei web application

CWE-119 (Improper Restriction on Memory Buffer)

The flaw resides with operation on a memory buffer that reads and write data outside of the intended boundary. If the hacker has control over the memory, then it is possible to execute the arbitrary code and also they can redirect the function pointers to malicious code.

It may also lead to corruption of memory and also a possible crash, in case of out-of-bounds read, the attacker can read sensitive information and by having details they can craft various attacks.

CWE-125 (Out-of-bounds Read)

The software reads the memory out of its an intended boundary, this allows an attacker to read the sensitive information and could cause a possible crash.

“A crash can occur when the code reads a variable amount of data and assumes that a sentinel exists to stop the read operation, such as a NUL in a string.”

CWE-78 (OS Command Injection)

Researchers observed that part of OS command using externally-influenced input, “but it does not neutralize or incorrectly neutralizes special elements that could modify the intended OS command when it is sent to a downstream component.”

Attackers could use this as an advantage to execute unauthorized commands to crash the software, read sensitive information and to access the restricted files and folders.

Swascan neither disclosed any details about the affected application nor depth information about the Huawei’s Web Applications. All the Vulnerabilities are evaluated by the Huawei security Team and fixed.

Swascan Co-Founder Pierguido Iezzi said: “In the world of Cyber security the principle of collaboration is finally establishing itself. The risks increase by a huge margin every year and this has mandated a cultural as well as technological Paradigm Shift. Our experience with Huawei shows that if these values are correctly understood they can be an additional backbone to create an effective and efficient Cyber Security Framework”.
