Summary
Beego has Collision Hazards of MD5 in Cache Key Filenames
In the context of using MD5 to generate filenames for cache keys, there are significant collision hazards that need to be considered. MD5, or Message Digest Algorithm 5, is a widely known cryptographic hash function that produces a 128-bit hash value. However, MD5 is no longer considered secure against well-funded opponents due to its vulnerability to collision attacks.
Understanding Collisions
A collision in hashing occurs when two different inputs produce the same hash output. For MD5, this means that it is theoretically possible, and even practical, to find two distinct cache keys that result in the same MD5 hash. This vulnerability has been well-documented and exploited in various security contexts.
Implications for Cache Systems
In a cache system where filenames are derived from the MD5 hash of cache keys, a collision could lead to several critical issues:
Data Integrity Risks: If two different keys collide, they will map to the same filename. This could result in data being overwritten incorrectly, leading to data loss or corruption.
Security Vulnerabilities: An attacker could potentially exploit collisions to manipulate cache data. For instance, by crafting a key that collides with another key, an attacker might gain unauthorized access to sensitive cached information or inject malicious data.
Unpredictable Behavior: Collisions can cause the cache system to behave unpredictably, as it may retrieve or store data in unintended files, leading to system instability or incorrect behavior.
Mitigation Strategies
To mitigate these risks, consider the following strategies:
Use a More Secure Hash Function: Replace MD5 with a more secure hash function like SHA-256, which has a significantly lower probability of collisions and is resistant to known attack vectors.
Impact
The application uses a cryptographic algorithm known to have weaknesses, such as MD5, SHA-1, or DES. Typical impact: compromised confidentiality or integrity of protected data.

Kodem intelligence
Severity tells you how bad this could be in the worst case. It does not tell you whether you are exposed. Exploitability and impact are functions of runtime truth: whether the vulnerable code is present, reachable, and actually executes in your application. A vulnerable package can sit in your dependency tree and never run.
Kodem, an Intelligent Application Security platform, uses runtime intelligence to reveal which vulnerabilities actually execute in production, so teams prioritize the ones that genuinely matter. Kodem's runtime-powered SCA identifies whether this CVE is reachable in your applications.

Frequently Asked Questions
- What is CVE-2024-55885? CVE-2024-55885 is a medium-severity use of a broken or risky cryptographic algorithm vulnerability in github.com/beego/beego/v2 (go), affecting versions < 2.3.4. It is fixed in 2.3.4. The application uses a cryptographic algorithm known to have weaknesses, such as MD5, SHA-1, or DES.
- Which packages are affected by CVE-2024-55885?
github.com/beego/beego/v2(go) (versions < 2.3.4)github.com/beego/beego(go) (versions <= 1.12.14)
- Is there a fix for CVE-2024-55885? Yes. CVE-2024-55885 is fixed in 2.3.4. Upgrade to this version or later.
- Is CVE-2024-55885 exploitable, and should I be worried? Whether CVE-2024-55885 is exploitable in your environment depends on whether the vulnerable code is present and reachable. A CVSS score is a worst-case rating; it does not account for your specific deployment, configuration, or usage patterns. Kodem, an Intelligent Application Security platform, uses runtime intelligence to show which vulnerabilities actually execute in production, so you can focus on the ones that represent real risk.

- What actually determines whether CVE-2024-55885 is exploitable, and how bad it is? Exploitability and impact are not fixed properties of a CVE. They depend on runtime truth: whether the vulnerable code is present, reachable, and actually executes in your application. A high CVSS score on a dependency that never runs is not the same as real risk. Kodem, an Intelligent Application Security platform, uses runtime intelligence to reveal which vulnerabilities actually execute in production, so teams prioritize the ones that genuinely matter.
- How do I fix CVE-2024-55885? Upgrade
github.com/beego/beego/v2to 2.3.4 or later.
