MalDet · Static Security Report
78 findings likely need attention, 22 look like noise. Most notable: Missing mutex unlock (`manager.ctxMutex` variable) before returning from a function. T... (99% confidence).
Generated from finding counts. A plain-English summary was not available for this scan.
MalDet scores two different questions separately, because they call for different responses: code can be badly written without being hostile, and hostile code is not always badly written.
| Detector | Looks for | High | Medium | Low | Total |
|---|---|---|---|---|---|
| semgrep | Insecure coding patterns across many languages | 15 | 90 | 0 | 105 |
| yara | Signatures of malicious behaviour in source files | 7 | 0 | 15 | 22 |
| guarddog | Malicious package and install-time behaviour | 0 | 5 | 3 | 8 |
78 of 135 findings were rated more likely genuine than noise by the classifier.
Identical findings are grouped, so a single rule firing many times takes one row. Ordered worst first. “Seen” is how many times that finding occurred.
| Severity | Detector | Finding | Seen | Example location |
|---|---|---|---|---|
| high | semgrep | Missing mutex unlock (`manager.ctxMutex` variable) before returning from a function. This could result in panics resulting from double lock operations | 1 | /psiphon/common/refraction/refraction.go:919 |
| high | semgrep | Untrusted input could be used to tamper with a web page rendering, which can lead to a Cross-site scripting (XSS) vulnerability. XSS vulnerabilities occur when untrusted input executes malicious JavaScript code, leading to issues such as account compromise and sensitive information leakage.

| high | semgrep | Calling `waitGroup.Add` inside of an anonymous goroutine may result in `waitGroup.Wait` waiting for more or less calls to `waitGroup.Done()` than expected | 1 | /psiphon/common/light/proxy.go:753 |
| high | semgrep | Detected non-static command inside Command. Audit the input to 'exec.Command'. If unverified user data can reach this call site, this is a code injection vulnerability. A malicious actor can inject a malicious script to execute arbitrary code. | 9 | /MobileLibrary/go-mobile/cmd/gomobile/gendex.go:90 |

| high | yara | YARA rule matched: detect_download_and_execute — Downloads a remote resource AND executes it - the actually dangerous combination, not just downloading alone | 2 | /vendor/github.com/pion/randutil/.travis.yml |
| high | yara | YARA rule matched: detect_obfuscated_string_execution — Reconstructs a string character-by-character or from hex escapes, then immediately executes it - fromCharCode/chr() alone are common in ordinary text-processing code, so this requires both the reconstruction and an execution call together | 2 | /vendor/golang.org/x/sys/unix/syscall_zos_s390x.go |

The application should consider leverage ATS public key pinning to ensure that the application only communicates to serves with an allow-listed certificate (and public key).

| medium | semgrep | Detected DES cipher algorithm which is insecure. The algorithm is considered weak and has been deprecated. Use AES instead. | 2 | /psiphon/common/crypto/ssh/cipher.go:463 |
| medium | semgrep | This code uses a 224-bit hash function, which is deprecated or disallowed in some security policies. Consider updating to a stronger hash function such as SHA-384 or higher to ensure compliance and security. | 1 | /replace/dtls/pkg/crypto/hash/hash.go:67 |
| medium | semgrep | Detected RC4 cipher algorithm which is insecure. The algorithm has many known vulnerabilities. Use AES instead. | 5 | /psiphon/common/crypto/ssh/cipher.go:57 |
| medium | semgrep | Iteration over a possibly empty map `set`. This is likely a bug or redundant code | 1 | /MobileLibrary/go-mobile/internal/importers/java/java.go:655 |
| medium | semgrep | Detected use of the functions `Math.random()` or `java.util.Random()`. These are both not cryptographically strong random number generators (RNGs). If you are using these RNGs to create passwords or secret tokens, use `java.security.SecureRandom` instead. | 1 | /MobileLibrary/go-mobile/bind/java/SeqTest.java:171 |
| medium | semgrep | The application's App Transport Security (ATS) configuration allows for insecure HTTP connections. The `NSAllowsArbitraryLoads` and `NSTemporaryExceptionAllowsInsecureHTTPLoads` property keys can be used to allow HTTP for all domains or a particular domain respectively.

| medium | semgrep | A session cookie was detected without setting the 'HttpOnly' flag. The 'HttpOnly' flag for cookies instructs the browser to forbid client-side scripts from reading the cookie which mitigates XSS attacks. Set the 'HttpOnly' flag by setting 'HttpOnly' to 'true' in the Cookie. | 2 | /psiphon/server/meek.go:822 |
| medium | semgrep | The application exports an activity. Any application on the device can launch the exported activity which may compromise the integrity of your application or its data. Ensure that any exported activities do not have privileged access to your application's control plane. | 1 | /MobileLibrary/Android/SampleApps/TunneledWebView/app/src/main/AndroidManifest.xml:11 |

The 'secure' flag for cookies prevents the client from transmitting the cookie over insecure channels such as HTTP. Set the 'Secure' flag by setting 'Secure' to 'true' in the Options struct. | 2 | /psiphon/server/meek.go:822 |
| medium | semgrep | Detected MD5 hash algorithm which is considered insecure. MD5 is not collision resistant and is therefore not suitable as a cryptographic signature. Use SHA256 or SHA3 instead. | 10 | /psiphon/upstreamproxy/go-ntlm/ntlm/crypto.go:24 |
| medium | semgrep | Detected SHA1 hash algorithm which is considered insecure. SHA1 is not collision resistant and is therefore not suitable as a cryptographic signature. Use SHA256 or SHA3 instead. | 8 | /psiphon/common/obfuscator/obfuscator.go:331 |
| medium | semgrep | `MinVersion` is missing from this TLS configuration. By default, as of Go 1.22, TLS 1.2 is currently used as the minimum. General purpose web applications should default to TLS 1.3 with all other protocols disabled.

Tags and branch names can be silently repointed by the action owner, enabling supply-chain attacks — as seen in the trivy-action and kics-github-action compromises.

| medium | semgrep | When working with web applications that involve rendering user-generated content, it's important to properly escape any HTML content to prevent Cross-Site Scripting (XSS) attacks. In Go, the `text/template` package does not automatically escape HTML content, which can leave your application vuln | 2 | /MobileLibrary/go-mobile/cmd/gomobile/bind_iosapp.go:17 |

| medium | semgrep | Checks for disabling of TLS/SSL certificate verification. This should only be used for debugging purposes because it leads to vulnerability to MTM attacks. | 5 | /psiphon/common/inproxy/webrtc.go:2449 |
| medium | semgrep | Detected a possible denial-of-service via a zip bomb attack. By limiting the max bytes read, you can mitigate this attack. `io.CopyN()` can specify a size. | 3 | /MobileLibrary/go-mobile/internal/binres/table.go:116 |
| medium | semgrep | Found an HTTP server without TLS. Use 'http.ListenAndServeTLS' instead. See https://golang.org/pkg/net/http/#ListenAndServeTLS for more information. | 1 | /psiphon/pprof.go:37 |
| medium | semgrep | Detected directly writing or similar in 'http.ResponseWriter.write()'. This bypasses HTML escaping that prevents cross-site scripting vulnerabilities. Instead, use the 'html/template' package and render data using 'template.Execute()'. | 4 | /psiphon/common/tactics/tactics.go:1386 |
