Platform Usage / Strings Bplist Files

Mobile AppiOS


Strings Bplist files is an IT vulnerability that affects platforms such as mobile apps and iOS. It is a type of vulnerability that leads to a lack of secure coding practices, and it is categorized under CWE-120 (Buffer Copy without Checking Size of Input) in the Common Weakness Enumeration (CWE) directory. According to the OWASP Testing Guide (OTG), Strings Bplist files can be exploited when a hacker is able to gain access to sensitive data stored in an application's binary property list (bplist) file, which is a file format that stores serialized objects.


Strings Bplist files can potentially lead to the data leakage of sensitive information, as the hacker is able to obtain confidential user data stored in the bplist file. This type of vulnerability can lead to a serious security risk, as the hacker could potentially access confidential user information that could be used for malicious purposes.


The best way to protect against Strings Bplist files is to ensure that secure coding practices are in place when handling user data. This includes encrypting stored user data and properly validating user input to prevent malicious users from gaining access to confidential information. Additionally, it is important to perform regular security audits in order to identify any potential vulnerabilities that may exist in the application's code.


The following is an example of code vulnerable to the Strings Bplist files vulnerability, with a description of the vulnerability:

// Vulnerable code
// This code attempts to copy the contents of a bplist file
// into a buffer, but does not validate the size of the buffer
// or the size of the bplist file

uint8_t buffer[1024];
size_t size;

memcpy(buffer, bplistFile, size);

The above code does not properly validate the size of the bplist file or the size of the buffer, which can lead to a buffer overflow if the size of the bplist file is larger than the size of the buffer. This can allow a hacker to gain access to data stored in the bplist file, which can lead to the compromise of confidential user data.
