# CVE-2024-28864: \[TagAwareCipher\] - Decryption Failure (Regex Match)

- Also known as: GHSA-RJ29-J2G4-77Q8
- Severity: CVSS 2.6 (Low), CNA
- Vector: CVSS:3.1/AV:N/AC:H/PR:L/UI:R/S:U/C:L/I:N/A:N
- CISA SSVC: exploitation=none, automatable=no, technicalImpact=partial
- Known exploited (CISA KEV): no
- Fixed in: 1.2.2
- Published: 2024-03-18 · Updated: 2024-08-02

## Affected

- IlicMiljan Secure-Props: from 1.2.0, fixed in 1.2.2
- ilicmiljan/secure-props (Packagist): from 1.2.0, fixed in 1.2.2

## Description

SecureProps is a PHP library designed to simplify the encryption and decryption of property data in objects. A vulnerability in SecureProps version 1.2.0 and 1.2.1 involves a regex failing to detect tags during decryption of encrypted data. This occurs when the encrypted data has been encoded with `NullEncoder` and passed to `TagAwareCipher`, and contains special characters such as `\n`. As a result, the decryption process is skipped since the tags are not detected. This causes the encrypted data to be returned in plain format. The vulnerability affects users who implement `TagAwareCipher` with any base cipher that has `NullEncoder` (not default). The patch for the issue has been released. Users are advised to update to version 1.2.2. As a workaround, one may use the default `Base64Encoder` with the base cipher decorated with `TagAwareCipher` to prevent special characters in the encrypted string from interfering with regex tag detection logic. This workaround is safe but may involve double encoding since `TagAwareCipher` uses `NullEncoder` by default.

## What to do

- Check your stack: if you ship or depend on IlicMiljan Secure-Props, ilicmiljan/secure-props, upgrade to a fixed version (1.2.2) per the references below.
